Google's advantage is also its Achilles heel: it is incredibly general purpose and searches the entire web.

Now how much of the web is all that useful? If a search results page on Google is just Google's opinion of what they think you want, what happens if you use a similar-enough algorithm but narrow the scope of the web you index to something more likely to contain information you can actually use?

Google today isn't even as useful to me as Google was 10 years ago. It has noticeably gotten worse. There has to be a fairly large niche there that several more specialized search engines could find a home.
