You mean 微博wei1 bo2, 博here means blog（博客）.
I see that you already have fans & people you have interested in,so I think you’re not level zero.~
In this way, you could add someone interesting, and you could receive their 微博,which are public to everyone. Also, you could decide to FYI or reply the 微博.
What’s more, you could use the chatting function, which is at the lower right corner of your web page. It’s fun to have a talk with your friends on 微博.
The above is for your reference,thanks!
