We feel fine is an interesting project which analyses recent blogposts and extracts information about what the world is currently feeling. Fun idea and I think they did a great job on the user interface:

“Every few minutes, the system searches the world’s newly posted blog entries for occurrences of the phrases “I feel” and “I am feeling”. When it finds such a phrase, it records the full sentence, up to the period, and identifies the “feeling” expressed in that sentence (e.g. sad, happy, depressed, etc.). “

I know about a few similar initiatives, for example moodviews which works with the content of LiveJournal. I expect a lot of tools like these, the blogosphere is full of valuable information that we don’t really use at the moment. There’s a lot of potential, for example in the field of marketing.

If anybody knows other tools like wefeelfine.org / moodviews, please drop a comment.
