What I am interested to know, and hopefully all you FB users can tell me ; is, I've heard that once you register on Facebook, its impossible to cancel your account, so all photos and information are 'out there' for eternity.
Well.... I was pestered by pals years ago to join Facebook, which I did and used it for a few years. But because I'm ill, I found it hard to see everyone I know getting married, having babies and going on exotic hoidays - and generally doing all the things, even the mundane little things, that I cannot do (don't get me wrong, I'm thrilled for my close friends but it was just having it all in your face and not being able to 'keep up'.
So, I considered doing a full delete of my account and never using it again (there is an option when you do this to have certain data, such as your photos etc emailed to you before/as you do this, so I'm told)... But I think at some point I may wish to join in again so I simply de-activated my account.
After about 4 years away, I fancied having a peek at what would happen if I re-activated my Facebook so I did so one night (in the early hours partly so that no one would be online and notice!
So I signed in and it was as if I'd never left! Photos and messages etc all there as before. However, when I de-activated it for a second time, it was as if I'd never been on Facebook.
I admit it's slightly disconcerting that one's data still exists somewhere out there but that was my choice and I could do a full delete if it bothered me that much.
And I have to say there were things I could have done to my account to make it work a bit better for me, for example making my privacy settings even tighter (I always had it set so that only friends could see anything I added or posted (and I couldn't be found if I was searched for via google etc). And I could've reduced the number of friends to only the closest and family (I did have a rule of only adding people I would tell or show stuff to in real life!)
So basically, if you want to be able to see other people's photos, and not to feel left out you can definitely make Facebook work for you, and I personally don't think there's any harm in it at all - it all depends how you use it! (In fact it's making me wonder if I should re-activate my own account and just use it on v low key level...!)
