TailRank, a popular blog news organizer that competes with TechMeme and Megite, has opened up its back end and will provide the service as a platform to application developers who would like to add a blog index and ranking service. The new service is called Spinn3r and goes live at around noon today. Rumor is it already powers Gnoos, which we covered last June.
Spinn3r indexed 1 million blogs. They are charging a monthly licensing fee per thousand blogs crawled, indexed, and delivered.
