I have family around the world, and we e-mail each other, attaching a photo if necessary, and can Skype to speak. No need to expose my details to all and sundry.
Faecebook reminds me of turning your house inside out, like a foldable girl's dolls house, so everyone can see inside, your photos on tha wall and your wall calendar exposed for all to see......
The bottom line is, anyone you NEED to see or communicate with will do so easily without it. Like the chap i first replied to said, you can join with any old alias just to have a peek and a trip down memory lane, then ignore it thereafter.
Like Bimbo, MyDisgrace, Tw@tter and NoFriendsReunited etc. it will soon become an expired fad - they know this which is why they are making hay while the sun shines by selling stock and going over to the advertising side.
I would happier buy mediacorp stock than Faecebook.
