I have a site at Blogbly.com that genuinely reviews and thus promotes topical blogs. If you have a blog or site that you are working on feel free to submit it. It's not an index like other blog review sites and is in beta but hey it's a free backlink and is getting great keyword traffic. Write up an excerpt 200-550 words about your blog and submit for editorial review. This is a genuine CTA! No spammy sites or terribly written excerpts.
