NetworkedBlogs.com is a Facebook application that helps you promote your blog.  Essentially, when you sign up, it will ask you to follow 5 other blogs.  There is a long list of categories and languages, so you will have no problem finding that meet your requirements.  You may enter in a profile about your own blog to add to their list.  The hope is that new members will see your blog in their directory and choose to follow you.  You will also see a list of blogs followed by all of your friends on Facebook.   It took about 5 minutes to set up so I would say it’s worth your while.
