I received my login to the beta version of the new blog search engine Sphere this morning. Founded by Tony Conrad, Martin Remy, and Steve Nieker, Sphere is a true blog search engine and not a RSS feed search engine, like Google Blog Search.
From the invite email:
“The primary focus of our product is relevance. We want to make sure the most relevant blog posts make it to the top of our results. We’re also working hard to ensure that our results are as fresh and comprehensive as possible.”
Search results look pretty good with post title, blog title, snippet, and how long ago the post was made. Each result also has a link to a “profile” which may be something blog owners can “claim” ala Technorati in the future.
