umm, facebook.com twitter.com these are main social sites you can also search through google search engine thanks
Depends on what your objectives are. I find Twitter is great if you want to really do user outreach. But facebook has worked better for me in terms of just having a strong presence.
hey you have to mention orkut first... if you mentioned then sure it contains max votes... my vote is for orkut only.. thanks...
Out of the ones you list Facebook. I like hupages too. Has anyone had good experiences with myspace for qualified traffic and if so what market segment?
I prefer using both of them, facebook and twitter. One thing I like about facebook is that you can chat with your friends who are online as well.
I don't like the way Facebook has become more like Twitter with the running news updates. Someone should make an app that lets you post to Facebook or Twitter, at the click of a button, while monitoring both news feeds.
This is like comparing apples to oranges to bananas..... Facebook is a social network Twitter is an update network Digg is a social bookmarking website never heard of the 4th one... Facebook, Twitter, & Digg are equally important for different reasons in my opinion.
