I have been using fb from last 7 years .FB helped me find so many of my childhood buddies. But it is too addictive. Posting your pics and seeing who liked it or commented it makes you too much stressed. People are now working out in whatsapp. I think fb would also become vanish some day like orkut.i like using facebook for video chatting and checking out pics for some special peoples.
It has one worst aspects is time is wasted a lot . even if you don’t wanna use also you would be compelled to use it.
