Did you know about BlogCatalog ?
It is a place to list your blog and make all kinds of blogging friends. You can join neighborhoods and communities. You can make friends and contacts. And it can help drive traffic to your blog. I have not been a member for very long, but already I can tell a difference in the increase in traffic to my blogs. I really like the community building it lends itself to. There are also discussions, you can build widgets, you can send private messages. All around, BlogCatalog is good for your blog.
