Wikipedia founder Jimmy Wales is launching a new kind of search engine – one based not on algorithms, but on the power of human collaboration. “[Search] is broken for the same reason that proprietary software is always broken: lack of freedom, lack of community, lack of accountability [and] lack of transparency. Here, we will change all that.”
Of course Wikia will be subject to the same games that spammers and SEO types play with conventional search results. As with Wikipedia, the quality of the results will be dependent on their being lots more good guys than bad guys monitoring and managing the content. But Wikipedia has shown that a helluvalotof people care; can and will pull together to make the model work.
