Very basic question which you can find with simple search in google, better if you've asked "How do you use your social networks"?

You still didn't answer my question, why do you use social networks, but I suppose your answer was good too, so what dos everyone use social networks for?

It matters what type of social network it is. If it is a general social network, then most people use them to connect with firends and participate in a community.

If the social network is organized around a specific topic such as Peace is Active or InvestEveryMonth.com, then people are there to find out more about the specific topic and to ask questions about something very specific.

Research shows that participating in social networks gives people a sense fo belonging to a community as well as becoming more familiar with whatever topic is being discussed.

i use facebook to keep in touch with my friends

I don't. I haven't really seen any compelling reason to.

I know what you mean Ezzaral, there's just no benefit for me to be on these social networks.

Not sure what you guys do online, but millions of people use social networks. Not only do they use them, but they can spend hours online while connecting with friends and participating in discussions.

That's what I'm here to find out, why they use social networks, maybe I will find merit in them.

Well, I use Facebook to keep in touch with people I've met in real life and know. I use Twitter to connect with people who share my same interests, and to get inspiration for new blog entries. So it really depends on the specific network.
