Michael Arrington at TechCrunch has posted a review of the soon-to-be-beta blog search engine Sphere. Arrington doesn't disclose many details, but provides a screen shot, and is generally wowed by the thing's relevance and design. From the screenshot, it appears that Sphere has some kind of smarts for distinguishing the topicality of a blog entry from the topicality of a blog. So it seems from the Related Blogs box on the search results page. The engine also evidently returns MSM news articles—again, in a set-off box—sort of the reverse of Yahoo!'s approach of bundling a few blogs into its news results. Sphere is accepting sign-ups for beta. [Thanks to Todd Carter]
