True. And also, keep in mind ... it doesn't truly have to be _better_ than Google search. You just need to start and maintain a _social trend_ so that the mainstream public _chooses_ it over Google. People use Google because it's the first and only option that comes to mind -- they haven't actually compared its accuracy to anything else in a long time (the audience of Hacker News is of course an exception).
