To be fair, from what I understand, it's almost impossible to completely delete your facebook profile
Totally. I hardly use facebook and have tried to close my account and it's highly annoying to only be able to deactivate it. I reactivated it with minimal data because I now live in Singapore and occasionally use it to keep in touch with a few people back in the UK.
What I dislike about facebook is more to do with us being subjected to beta testing for the future facebook, which will be completely ad driven, and that they are selling data to marketing companies as we speak. I wrote a story on companies hired by Sainsbury, Nike and others, trawling through peoples Wall postings, likes and dislikes, groups and links, and even personal private messages compiling demographics data.
All those silly little games are just testing the viability of bigger, monetary driven programmes.
And as for letting you post your mug AND address and other personal details -- well, I don't think facebook should make that so easy (if you want to, you should opt in, rather than have to opt out) since that just gives insurance and bank fraudsters an easy time (not necessarily to clone your details, but to provide addresses)
I wrote another story about that -- you'd be amazed how truly globalised organised fraud gangs are and how long they take (paying talented but poor IT whizkids to go through school years before they take part in any crime) in their efforts. A huge public database of names, faces, addresses and other personal data is just handing stuff on a plate to some people....
Now yes, if you post something on the Internet it's not private, but facebook suckers you into to thinking this info is confined to its walls.
There is a good reason Microsoft (which already paid for a 240 mln dollar stake in facebook, valuing it THEN at $15 billion, Li Ka-shing owns another $120 mln) is trying to take it over. When it goes ad-driven, its going to be huge. If it tries to IPO instead, financial analysts are talking in terms of $20 bln.
