I should stop saying "relevant." Searchers want "useful" not just "relevant" and there's a world of difference. G was providing relevant pages in Florida/Austin, but most of those .gov, .edu, and bookseller sites were certainly not "useful."
So what happens next?
Yahink will tighten up as time passes, and get better at weeding out spam. (It was easy to game G two years ago too.)
Meanwhile, G has already made good strides with Brandy. If it can dump more of the .edu and especially the bookseller listings, things could get interesting. Then of course M$N still looms. Remains a three horse race IMHO, although G has certainly lost most of its advantages...
