Having observed that major search engines often seem to hide what I'm actually looking for - web search results - "below the fold" (assuming it's there at all) I can't help but wonder if there is an opportunity for building niche "web search" engines that search the web (rather than the adverWeb, the seoWeb, or the goog/twit/faceWeb.)

As I've mentioned before, my favorite flavor of Google is Google Scholar. I'd also like to be able to slice/subset search results to get scientific, non-commercial, public interest, etc..
