Any new google will become the current google because it will be gamed. I agree with the parent poster about hand-curated directories being the key to finding better stuff. It's necessarily much more distributed - because one person can't index everything - and therefore much harder to algorithmically game.

Google has conditioned us into thinking that "an algorithm that automagically separates the wheat from the chaff" is the only way to do things. It worked for them for a while, but the adversarial forces of marketing, spam, malware, etc are very creative and fast-moving, and that's a lot for an algorithm to try to constantly reckon-with, so best case it'll probably stay a stalemate.

But that's not the only way things can be.
