As I said earlier fb actually draws your attention all the time and you go crazy about it, but when actually use it normally, it is actually a gift for you.
Using since 8 years from now, gives me the feeling of togetherness with friends and relatives.
There is no other alternative for Facebook, there are no competitors for it, although twitter is there but it actually in a different path. I love to be in face book but not all the time just check it out in the evenings like we check emails.
