Wikipedia

Wikipedia founder Jimmy Wales is targeting the fourth quarter of this year for the unveiling of an open-source search engine that he hopes could challenge the dominance of market-leaders Google Inc. and Yahoo Inc.The project is being run through Wikia Inc., a for-profit company founded by Wales that seeks to use a similar model to the Wikipedia community-written and edited encyclopedia. He hopes to provide the tools and technology to allow programmers across the Internet to collaborate on the development and testing of a search engine and make the results freely available.
