Interesting article. Thanks for posting.
Yeah i just turned my FB off. Didn't delete it as there are contacts there with people i met overseas and such (i remember when it was just email addresses you swapped).
one good thing i did was to download all my friends email addresses. Basically send it to yahoo and then you get a CSV (text) file of all the emails.
Then i imported that into my gmail.
I also downloaded all the info i had into a .zip file. There is a part on FB which does it for you. They send you a link and you can just download it. handy stuff
Eventually i will delete it all though.
