This guy wrote a BBC News scraper that links with key phrases on Wikipedia and tracks references in the blogosphere (that term really rubs me the wrong way) via Technorati.
My RubyGems GUI is coming along. Last night I actually installed a couple of packages with it. I still need to write the uninstall code and fix some dependency resolution issues, then it will be ready for public consumption.
For those of you using LocalFark, they made a small change to the HTML on the front page which broke the LocalFark scraping. I've fixed it here at home, but I'll need a little time to package up a new release.
