People could have various reasons to use a social networking site such as Facebook. To communicate easily with people, to play games, to kill time, to advertise their business and so on.
So, why do I use facebook?
I simply use it to keep in touch with friends and family, specially those who live far away.
There are just so many features available on it like status updates or posting stuff on another person's wall, I won't even try to list everything out.
Oh and I think the 'Poke' feature is a pretty unique idea :P
Basically, I use it because I think it's a lot better than other social networking sites. And yes, I'm just a little obsessed with it :P
