ScraperWiki is all the tools you need for Screen Scraping, Data Mining & visualisation

I've written a little program to find out. It works by extracting the comments from the source code and feeding them into Synesketch, a textual emotion recognition and visualization engine. The program ignores documentation comments, because those are written for public consumption. I'm only interested in the comments used for private communication between team members.

Datamob highlights the connection between public data sources and the interfaces people are building for them.
