'Don't Be Evil' Tool for Google Search, by Facebook, Twitter Devs (pcworld.com)

tl;dr: Changes Google's "search plus your world" to include other social networks (Facebook & Twitter being biggest). Released as open source code.

This was already submitted earlier today [1] by Blake Ross, who is probably one of the original authors. It has been on the front page all day.

The Hacker News guidelines [2] suggest submitting original sources, so it would have been better to submit the actual website (like Ross did), as opposed to a PC World article talking about the website.
