Jimmy Wales, founder of Wikipedia, talks about his new wiki-styled search project in the video below. Wales hopes that second-tier search engines might want to join the open-source project and go after Google (GOOG).

He considers all search engines besides Google and Yahoo (YHOO) to be second tier. So, that includes IAC's (IACI) Ask.com, Time Warner's (TWX) AOL, and Microsoft (MSFT) Windows Live search.
