"If Google wants to avoid becoming the next Yahoo (or AltaVista or Lycos) then it needs to think about how it can best serve its users with more relevant results." They do that all the time. Plus: Just because Google is dominant right now does not mean that everybody else will be into search. I wonder why people try to convince us that Twitter is about search while it is a social networking platform per definition. It can be used as social news or social bookmarking but even its rudimentary real time search feature can't replace Google.
