Google r eleased its “+1” social feature, which basically adds its own version of Facebook’s “Like” button to web search results and will eventually apply to ads, too. So when users search results with the feature enabled — right now, you have to opt in, but eventually it’ll roll out to everyone — they’ll see a small clickable “+1” button next to each result, indicating to friends within their Google social graph which stories, posts, videos, etc. they enjoy. When +1 hits advertising, expect those search ads to be even more targeted to your preferences. (Fortune)
