Wikia is a new Web Sercher. The final mission is compite with Google, but first impression are very unfortunate for wikia. Is Open Source based and its algorithm is based in social content. Is based on three Apache projects Nutch, Lucene y Hadoop. Is interesting view as Google and Wikipedia are fighting to make compite, because google will introduce a Wikipedia similar system. Really interesting the figth, I hope it will be better for the final user.
