What am I doing here?

I registered in this social network. I wanted to blog here. I wanted to learn from others how they design blogs. But no one blogs here. I wanted to comment on other people's blogs. But here, everyone's blogs are empty. I don't understand why people design their profile page so much if they are too lazy to write a few words to the blog later. Users here only write meaningless questions in Bulletins to get meaningless answers. Then why is it a social network? It's just a stupid chat. What am I doing here?
