InfectiousGreed :: Google's ranking algorithm, like any trading algorithm, has lost its alpha. It no longer has lists to draw and, on its own, it no longer generates the same outperformance in part because it is reverse-engineered, well-understood and operating in an adaptive content landscape.
There are two things that can happen now, e.g. we could head back to curation, which is what Paul Kedrosky sees happening, and watch new algorithms emerge on top of that next-generation curation again. Think of Twitter as a new stab at curation, but there are plenty of other examples.
I wouldn't say that we will face the dawn of search. And for me personally Facebook and the social graph is not a substitute for searches on Google. I still "google" if I want to search. But I agree with Kedrosky, that we can currently observe a new trend. Google build a great tool (its algorithm) to understand the needs (expressed as keyword searches) and Facebook explores the social graph especially the constructs "attitude", "opinion" etc. But Twitter outperforms along the social interest graph, which is far more interesting from my point of view, because it is a shared interest which connects people.
