What about additional information on encyclopedia quality pages that would normally have been excluded? It seems like anyone could make an extension site to wikipedia where articles that aren't allowed at wikipedia could find a home, and the search there could also search wikipedia. The issue seems that nobody wants to put the hard work into making this happen, marketing it, and managing it. They just want wikipedia to do it for them, using the limited resources wikipedia has at their disposal, for free.
