Sphere
Sphere is a blog search engine focused on discovering high quality, relevant blogs on a timely basis.
It starts with relevant results and fast performance. Our new relevance-based algorithm discovers new blog posts as they’re created, indexes them within minutes of being published, applies rich semantic analysis and makes them searchable by relevance or time. Plus, we’ve got a few fun, helpful features that we think make for a richer user experience.
UPDATE 6/6/2006:
Sphere has been released.
