"I think that the right model for content discovery is either crowd sourced by a like-minded community" and now you've re-created the original Yahoo search, which was killed off in the original Search Engine Wars by the likes of AltaVista and later Google because it didn't take long for the amount of new content on the web to overwhelm the manual curation process. A manually curated system can only truly work with a constrained domain of content/subject matter and tolerance for high lag regarding new information. Wikipedia is an example of what that kind of system would look like.
