So blog friends, if you haven't already- sign up on BlogFrog. It walks you through an easy process, scans your blog for links and you are set up! You can see what people share similar friends and links as you; and find blogs of people you may know from high school, college, etc. And you can put their little visitor gadget on which is fun too to see who stops by!
And FOLLOWERS on blogger is great too. You can add it by going to your layout page, click 'Add a Gadget' then install the Followers! Then me and others can follow you! Blogger will keep track of when new posts are coming up and it is handy.
