At the core of We Feel Fine is a data collection engine that automatically scours the Internet every ten minutes, harvesting human feelings from a large number of blogs. Blog data comes from a variety of online sources, including LiveJournal, MSN Spaces, MySpace, Blogger, Flickr, Technorati, Feedster, Ice Rocket, and Google. We Feel Fine scans blog posts for occurences of the phrases “I feel” and “I am feeling”.
Here’s a serendipitous screenshot. I really dig the information design they’ve used to render the results–it’s whimsical and playful yet pretty intuitive. The site has a very similar mood to PostSecret–it feels very personal and voyeuristic.
