Wikipedia's founder Jimma Wales today unveiled an alpha version Wikia, this project is a new opensource search engine.
Wikia is working to develop and popularize a freely licensed (open source) search engine. What you see here is our first alpha release.
We are aware that the quality of the search results is low..
Wikia's search engine concept is that of trusted user feedback from a community of users acting together in an open, transparent, public way. Of course, before we start, we have no user feedback data. So the results are pretty bad. But we expect them to improve rapidly in coming weeks, so please bookmark the site and return often.
Right now, the most important thing you can do is help with the "miniarticles" that appear at the top of popular search terms.
