I think human powered search could be achieved by Google. All they need to do is track our clicks on the serps and interpret which sites are good. Rotate all sorts of sites in the serps and gradually build a database. The whole thing would be like a wiki, with everyone contributing a little, and benefitting from the whole. The only way to accurately beat spam and low quality is to use human feedback. They probably do use human feedback already, just in a different way.
I'm wondering if reddit and Facebook could use this approach to build search engines. They do have large databases of human preferences.
The machine learning (AI) approach:
Another idea would be to distill information from the web Watson-style and try to answer many questions directly instead of redirecting to external pages. So far Siri, Watson, Wolfram Alpha are ahead in this field.
