Actually I would eventually consider re-opening a Facebook account should they introduce an alias/identity system so that I could manage easily and separately my différents circles. Of course ads profiling of each identities should also be kept separated. And of course a strong privacy statement backed up by some technical information on the architecture should also be a part of that change (Apple iOS security guide is a good example to follow IMHO). Unfortunately this look so far away from the current Facebook approach to new users "hey trust us type in your IMAP credentials so we can scrape all your acquaintances by snooping all your mails!"
