What do you think?

I have found a couple of websites where I can list my blog (like Blogwise, and Blogmatrix. I don't know if I want to do that though. On the one hand, I like the thought of new people reading my blog, but on the other hand, I like the coziness of the small group of readers I have now. So, should I, or shouldn't I? I guess I think that if I do this and get more readers, they will probably be spoilsports who nitpick and criticize. And who needs that?
