I'm not convinced it is gameproof yet kickaxe. Merely saying that I believe it is a step in that direction as it seems logical to me that Google wants to get to a point (one day) where Webmasters cannot artificially boost their SERPS.
It's why I think many types of links are slowly being devalued, why much META data is now ignored, why KW density is less important than it was, why I think the TITLE and H1 tags will eventually become irrelevant (to ranking anyway) and why I think that user reactions to a page (however that is measured) will become the de facto way of measuring quality content.
But I think they are still some years off fully achieving that. This is just one small step closer IMO.
I'm already convinced that improvements on some sites I manage are down to user behaviour anyway.
