I made this giant list/directory of directories for blogs. Everyone with a blog should submit it to as many directories as possible. I have almost finished the list myself and my backlinks have greatly increased and my page rank went up too, but nobody really knows how that works so I don't know if that matters or not.
If you don't have an RSS feed for your blog, try Feedburner.com and set one up then submit your blog to all of these RSS search engine directories.
