Yahoo! Search Builder: The idea is great: the power of Yahoo!’s search engine with its colossal database with all the advantages (no spam) of supervised indexing. In fact, niche networks (groupd of people) will probably use this new service to make search engines for their niche domains and will meticulously add new crawlable sources over time. That way, no spam website will be indexed, the results will be much more accurate and useful and the result will be that users will spend less searching time.

Other search engines [Rollyo and Eurekster] already do that. The main difference is that they developed “social” features around the search results and Yahoo! didn’t. Some people think it is sad, but personally I think that Yahoo! just don’t care. Social features are cool, but for some purposes only, not for everything. But personally, the big difference is Yahoo!’s database compared to Rollyo’s and Eurekster’s.
