Sphere is a new startup competing in the blog search engine space.

We are strong believers in the blogosphere. We hope Sphere, focused solely on returning the most relevant user-generated content, will help readers explore the blogosphere more effectively, and perhaps inspire many to become bloggers themselves and contribute to the ’sphere.

Sphere is a new kind of blog search engine that uses an advanced algorithm to discover high–quality, relevant, and timely blog posts. It’s a very simple idea, but really hard to do. What makes us better than other blog search engines? Our new, advanced algorithm:

• discovers the most relevant blog posts as they’re created
• indexes a blog within minutes after it’s published
• applies rich semantic analysis
• makes blogs searchable by relevance or time
