I've created a list of high page rank (minimum 4) directories where you can submit your blog/site for free. I don't want to list popular directories like DMOZ and Yahoo, because everyone alreay knows them. I only listed lesser known ones with high page ranks and SEO-friendliness. I hope you find it useful in search engine optimization of your sites. Stay tuned, I will be adding more. Please let me know if you know great directories.
