This could change small parts of the world economy couldn't it?
Seriously though : what is important about this is that GG has effectively confirmed that there is human input into the serps.
I don't think this is direct input - it is almost certainly indirect.
My gripe is this :
1) this human input has always been denied.
2) if there is a human input, then maybe more notice should be taken of individual webmaster queries:
e.g. "my site has disappeared" can no longer be put down to "it's our math algo, sorry pal."
