Is This The Future Of Search?

In fact I think Google already has these ways, with Google Toolbar, Google Analytics and Adwords tracking users behaviours among other things.
So I suspect, if this voting stuff comes, it would be more psychological than technical? Maybe people are happier with a site if they are allowed to "vent".
A bit like the escalator engineers who placed mirrors next to the escalators so that people would not notice the waiting time so much. It doesn't improve the technology, but makes people happier.
I am very enthusiastic about Social search and even built one (with the same commenting, voting features).
Wikia is doing the same, so, nothing new about this for people like me, but, feels great to know that Google is atleast 'experimenting' with social search.
So for the many people who are not able to use the new search feature (like me) - this is a great help to visualise where Google is trying to take it.
What would be fantastic is if Google could weight these votes based on how "alike" the person voting for it is to me.
EG, if I was interested in say, Kung Fu and Knitting, and there were other people interested in Kung Fu and Knitting, then the options that they vote for would be more relevant to me than someone who was doing SEO work on those various sites. So hopefully those would rank higher.
