I've been thinking in this same direction. Especially the community-driven part. Google seems to be more interested in what corporations and advertisers want, rather than what users want. With their tendency to crowd-source their AI training, I'm surprised they don't let users vote on search results. If I were to make a search engine, I'd definitely give users more control over their results. Block crap sites, vote up your favourite sites, vote down questionable sites, maybe different context profiles, because if you're searching for Java in the context of vacation or news events you want different results than if you're searching for it in a programming context. There's so much that search could do better than what Google is doing, but I'm not doing it because it's way too much work, and it requires serious resources to index everything.
