Venture Beat cited an article published today @Business Week that twitter is profitable. I know what twitter is. Actually, I have an account there but I haven’t used it much. I didn’t see too much action there, well, because I didn’t use it much.

Now I’m thinking. I haven’t really kept up with all of those. It’s probably about time for me to start using some. The social media, some of which started as media for small circles, has grown so much virally. We hear about twitter and facebook almost every day on TV.

I’ll probably explore other social media also, such as Digg and Delicious.
