Opinmind Opinion Finder

Opinmind "is a fun tool to find positive and negative comments by bloggers on any subject imaginable."

There needs to be a way to edit what's positive and negative, however. For a search for biotechnology, I found on the positive side an opinion " So when I say that the dangers of biotechnology are great and irreversible that because they are." Obviously, the algorithm choose "biotechnology are great". So, opinmind is a tool for gathering simple statements only.

That's just my opinion!
