Opinmind Splits Out Positive and Negative Blog Views

Michael Arrington is pointing this morning to Opinmind, a new blog search engine. The site's unique proposition is that it helps users find people that share interests. I like how it separates positive and negative opinions. Keep in mind that the results aren't statistically relevant because it only samples 1.7 million blogs. Still, over time I can see free services encroaching on the value of the larger paid enterprise tools, like Intelliseek.
