Well that's one way to break out of the filter-bubble/echo-chamber I suppose. If only our best search technology was based on something better than a popularity contest :(
This holds true for most topics I can think of. Moreover, if I ever need to read Wikipedia and such, I already know about those websites, and I can go there directly - no need to search. Shouldn't web search engines act like discovery tools?
If your business model is based on advertising that depends on masses of page views to generate value, then no. You want to be as generally useful as possible so that e.g. people use you as an (extremely inefficient) DNS service.
(Google Labs has a single optional feature available for search. Perhaps their arch doesn't make 20% or Labs projects a good fit for plugging in extra fancy search features?)
