This week Google's Eric Schmidt suggested we may need to invent new identities to escape embarrassing online pasts â€" while Facebook launched a tool to share users' locations. So does technology pose a threat to private life?

Are you in a relationship? What are your political views? And where did you go for breakfast this morning? What would once have been details of our lives known only by those we know and trust, many of us now willingly display online.

From the surveillance entertainment of Big Brother to CCTV and celebrity magazines, the boundaries of what is regarded as appropriate to put in the public domain are shifting dramatically. But nothing is challenging our notion of privacy more than social networking, with 26 million of us using Facebook to share the minutiae of our lives every month in the UK alone.

Facebook has proved irresistible to many because we are lured into joining by friends and family. Browsing, reading, comparing and nosing is instinctive, impulsive and reflects our tendencies offline, our "social graph", as Facebook founder Mark Zuckerberg likes to call it. Having executed the social networking business idea better than its rivals â€" MySpace, Bebo, Friendster and Hi5 have been left for dust â€" Facebook has seen astonishing growth, from a Harvard dorm project in 2003 to a global phenomenon that had 500 million monthly users by July this year. That's already one in 13 people on Earth, and Zuckerberg recently predicted it was "almost a guarantee" that his site would reach 1 billion users, with growth in relatively untapped markets such as Russia, Japan and Korea "doubling every six months".

On Thursday, Facebook unveiled its latest gambit in the battle to remain top of the social networking heap with a move into geolocation services, which harness the GPS functionality of increasingly powerful mobile smartphones. Facebook Places will launch first in the US and later in the UK, allowing users, if they choose, to share their location with friends on the site by checking into public venues. Sensitive to intense public scrutiny of its privacy controls, Facebook was careful to make the service opt-in but every geolocation service â€" including Google's Latitude, Gowalla and Foursquare â€" has prompted renewed debate about the protection of personal details online.

"This is a seminal moment where we're seeing new thinking and new practice starting to emerge around the issue of privacy," says Stephen Balkam, chief executive of the Family Online Safety Institute and member of Facebook's safety advisory board. "The battle lines are being drawn between generations. Facebook is headed by someone who hasn't hit 30 yet, but has very different perceptions and assumptions about what is private and what is not. We need to recognise that with social networking, geolocation and digital technology, the privacy bar is being reset."

Facebook has come under significant pressure to make its site safer for users. Incidents of serious crimes facilitated by the internet such as the murder of British teenager Ashleigh Hall by Peter Chapman earlier this year, are tragic but rare. More common is the embarrassment from a compromising tagged photo of a drunken night out.

The rapid pace of development by technology companies often throws up new cultural and ethical challenges. Google's Street View has frequently been challenged by privacy campaigners who question whether the logistical and commercial benefits of making every property in every street visible on the web are worth the sacrifice of the individual's right to privacy. Facebook users first raised their pitchforks in 2006 when the site introduced a news feed for each user, summarising their friends' activity. More recently it came under pressure to simplify its privacy controls with some high-profile commentators and groups â€" organised on Facebook pages, naturally â€" encouraging others to remove their profiles. It responded in May with simplified privacy settings.

Balkam describes the internet's two biggest privacy problems as reputational damage â€" inadvertently posting drunken photos that your boss might see, for example â€" and physical safety, the latter being the issue for women particularly wary of location tools. Burglary is another concern, when users of location services announce they are out of the house; in February three developers built PleaseRobMe.comto raise awareness about the consequences of broadcasting space in the public audience.

Currently location games such as Foursquare, where users check in at public venues to earn points and prizes, tend to have a small, enthusiastic and largely trustworthy group of dedicated users comprised of so-called "early adopters". For them, this period of intensive invention and opportunity is a golden age. Christian Payne â€" who describes himself as a "social technologist" â€" abandoned a career as a photographer in early 2008 when he had a "car crash epiphany". Within minutes of tweeting a video of his crashed Land Rover, he had an offer of help from a local crane operator, his AA membership number sent to him and a call from BT asking for the serial number of the telegraph pole he'd crashed into. He worries that spirit of helpfulness will dilute as social media becomes more commercialised, and its users more sceptical.

"We'll never see it like we do now â€" more nefarious people will come later," he says. "But it would be more risky for me not to take the chance of building meaningful connections with acquaintances who then become friends when one of you needs some help."

Payne seems to put a lot of intimate information into the world, but still skillfully manages to keep his personal life, and that of his partner and son, almost completely private. It's up to the user to decide what they want to keep private, he says, though he's uncomfortable with the idea that he is unknowingly creating a public persona for himself. "I'd hope I'm doing this naturally and not thinking about it. But then asking me that is like taking me out of the play I'm acting in as myself â€" and asking me to direct it."

Online privacy is intrinsically linked to identity. Author Peggy Orenstein recently that her reflexive compulsion to tweet a pleasant moment with her daughter had also spoilt the moment, and mused that our online personas are elaborate constructs that we, knowingly or unknowingly, craft into an identity we want the world to see. The internet has provided a platform that seems to challenge us to present a single identity to the world, yet we struggle to balance the profiles we share with family, friends and work colleagues.

Part of Facebook's success has been to demand people's real identities. In that way, it represents the maturation of the internet where the previous norm had been a wisecrack pseudonym and a world of "trolling", where faceless, nameless commenters could easily post abusive messages and attack each other. The improvement in the quality of communication and debate online is in no small part down to the trend towards using real identities. However, anonymity still has its role in whistleblowing sites such as WikileaksOr in debates, where the contribution to the debate about rape, for example, need protection.

If you think the current internet landscape is frightening, don't think too much about what's coming next. Already served with targeted ads based on keywords in our Google email, or picked out by our age and interests on Facebook, the future is more personalised still. "Sites will get much better at filtering information and predicting our behaviour, serving us what we want to buy and finding new ways to share information, like location. Three years ago, people wouldn't even have dreamed of sharing their location," says Wright. While the sensitivities and sensibilities of managing our online data still need to be clarified, there will be benefits in personalisation, which promises more meaningful, relevant advertising for consumers and consequently, for advertisers, far more effective bang for their buck.

So what next? Three years ago, rival social networking site MySpace seemed invincible. Could Facebook still lose its edge? Anything is possible.

Balkam recently proposed Facebook to recruit philosopher help interpret some of the difficult and unprecedented ethical and sociological challenges it faces.

"No company in the world has ever attracted 500 million users, and they are having to come to terms, at lightning speed, with what is good and what is abhorrent behaviour. Aristotle and Plato struggled with that â€" and the average age at Facebook is 28."

Where Twitterati hell

Zoe Margolis, blogger

While I'm very active on social networking sites such as Twitter and Facebook, I have so far avoided all the location-based tools on my phone. Primarily, this is because I do not want to publicly announce where I am - I wish to protect my privacy and safety - but also because I don't want to bombard people with incessant, dull, information; I've unfollowed people on Twitter and Facebook due to their too-frequent (and, might I say, very annoying) Foursquare updates being fed through to their timelines.I can see the point of location tools â€" they're an easy way to connect peoplewho might otherwise be unaware of their proximity to their friends â€" but given the amount of information we already share using social networking sites, it almost seems like overload to add yet another method of input, and it's pretty much redundant if not all of your friends/social circle are using the same tool.

I have some major concerns with Facebook Places though and believe it is a huge threat to people's privacy. It is already live in users' settings(though the feature has not yet been rolled out in the UK) and while there is the option of limiting the location info to friends only, they have to de-select the automatically enabled "Include me in 'People Here Now' after I check in" box in order to opt outof their location being included on a public list for all to see.

In addition to this, people's friends can "check' " them into locations, so even if someone has limited the information about themselves that they are sharing, there might still be a breach of their privacy from others.

Most of my friends on Facebook have never heard of fourSsquare or Gowalla, let alone used a location-based tool on their mobile phones; I assume the majority of people who use Facebook are similar. Given this, it concerns me that Facebook Places appears to be lacking transparency about privacy. The ability to change the settings to ensure personal information is protected seems more geared to the tech-savvy, than the lay-person; I fear many people will discover their privacy has been breached only after the event.

David Nobbs

I don't believe total privacy is possible so I never telling anybody anything on line that I wouldn't be happy for the nation to know (if it was interested!).

I think some people are so hungry for celebrities, they 're happy not to have a personal life in general. I 'm very careful with my Tweets. People can never be quite sure whether they 're true or false, and I never show when I' m leaving.

Sorry this is so short but I'm off to Portugal now for five months. Only joking.

Max Tundra,musician

I probably spend too much time online, sharing details about my life with anyone who has the remotest interest in my music. I don't like the idea of letting people know exactlywhere I am right this second, but as my fans tend to be fairly sane and unstalkerish, I feel comfortable letting them know what I'm up to in a general sense.

I don't use Ffoursquare or any applications which might reveal my geographical co-ordinates, although I am often easily locatable, as I play advertised concerts. I did, however, recently delete my personal Facebook profile, as that seemed to be a cluster of unnecessarily pertinent information about my life and the people I share it with, as well as being a colossal waste of time which could be better spent telling people on Twitter that I prefer the Henry vacuum cleaner to the Dyson.

Graham Linehan, comedy writer:

I always hated Facebook because it made me very uncertain about what I was and wasn't sharing with the world. The privacy settings were, famously, a bit of a maze, and seemed subject to sudden changes that you hadn't agreed to. I felt like one day I might open up the site to see a picture of myself in bed asleep with my wife, like in Hidden'.

Twitter is different because it forces you to be very selective with what you choose to share, and so forces social media back to a more private place. I personally don't tweet much stuff about my home life, because I don't want to accidentally tweet something stupid like "Holiday starts tomorrow!" along with a geotag to my home address. So my tweets are generally links to things I find funny or interesting, and my home life only gets a look-in when something truly interesting or funny happens.

I think people should start to claw back as much privacy as they can. Services likesuch as Twitter show that it's possible to share selectively. Sharing selectively should be the default setting on every social network service. Which, again, is why you won't see me on Facebook any time soon.

John Prescott, politician

Twitter was a revelation. In the past, if I should get a message from I 'D must convince the newspaper to publish it. Now I can tweet my thoughts and if it's interesting, it's LL 'get ready to collect. My Tweet Milburn ran on rolling news within 10 minutes.

I share a lot of content like my blogs and vlogs along with links to stories and virals from others I like. Twitter is also great to run campaigns and organise tweetups.

We did the first pastiche of the Cameron airbrushed posters, which then inspired mMyDavidCameron.com. Suddenly hundreds of thousands of people were doing their own versions. It destroyed Ashcroft's poster campaign and cost nothing.

And when the founder of the National Bullying Helpline said people were bullied in No10, someone tweeted me a link to the industrial tribunal which proved she was accused of bullying herself! It killed the story within 24 hours.

I've found Twitter to be a fantastic way to communicate, learn from others and show the real me, not the distorted view peddled by the media.

But I'm not convinced about geolocation applications. You have to have some privacy.

Suzanne Moore, journalist

Don't mistake personal information for honesty. Personas are created and people play as well as tweet their hearts out. If you don't want to bare your soul you don't have to, but the dividing line between public and private is now generational, one that neither mainstream culture nor government appears to understand.

I don't much care what people think of me and was wondering who some guy on MasterChef was the other day on Twitter and wondering if I had slept with him. Turns out I hadn't which was a relief. And a joke!
