You start to get it. We basically use Wikipedia content to build the semantic Web and try to dramatically improve the search results quality. We build the meaning based Web.

The purpose of the explore feature is to save time for the user in the search results analysis process and get higher quality results : go straight to better results. As the community grows, the Webzzle results improve. It's the knowledge network effect.
