I am not into any of social networks. I use FB but not that much. I like language sites more.

i like  instagram because through it u can share ur pics only there is no chance to ppl to share anything else just like facebook ..the ppl start to post anything the do even the silly things 

I use FB only. It's easy to use and I have keep in touch with old friends there. I'm too lazy to sign up for any other social netwoking sites. I don't know how people manage having all these multiple accounts in different places! I would go crazy. :)

I'm addicted to Twitter.

for me I like Facebook more. through Facebook I exchange ideas with my friends easily.
