"Was this link Useful" with Organic Results

Ultimately good or bad?

Got the "Was this link useful" buttons for a organic search.
Luckily I was doing a real search and not scoping out a competitor.

I assume Google has already factored in that the percentage of webmasters who purposely voted "no" for their competitors would account for neglible amount of data among the millions they are showing this to? ;)

Will it be open to abuse?

(I can hear the blackhatters typing up scripts right now)

Actually, I wouldn't mind a G employee commenting on this.
Vanessa? GG? Adam?

Any rhyme or reasoning to who gets picked to utilize this precious tool?
Is it random or are you using specific parameters?

Anyways, just went through some known serps that have those nifty little .edu redirects to spam pages and clicked "no".

and even if all sites install analytics and google starts using user data more we will be all building scripts visiting competition sites for just 1 second :)
