Sidepoint from the main purpose, but I also like the unobtrusive buttons for positive feedback. I'd really like a search engine where I could upvote or downvote domains. There are a whole series of searches where I get an understandable result that I'd personally never prefer. ie, maybe a user hates McDonald's and wants to bury it from nearby food results, or prefers the user experience on Wikipedia over imdb when searching for movies or actors. Or maybe a spammy experts forum somehow climbed the rankings by towing the line of acceptable site behavior, I don't know. I feel like Google experimented with something like this for a while then pulled it, but I can't find records of it... If my votes affect search rankings for everyone else, it could be easily gamed, but let me at least control the rankings I personally see.
