Jimmy Wales, the creator of online encyclopedia Wikipedia, is working on an open source search engine:

The new site, due to launch by the end of 2007, will combine human-assisted editing with computer-controlled searches. Earlier this year Wales’ commercial startup company, Wikia, purchased the rights to web crawler platform Grub.

Grub users download a program which makes uses of their computer’s processing power while the machine is left idle. If widely adopted, such an arrangement could reduce the need for Wikia to set up a web crawling network of its own.

Let’s hope it’s a more reliable source than Wikipedia has become.
