Noticed a new +1 icon in my search results and just saw that the news of this has hit their official blog
Today we’re taking that a step further, enabling you to share recommendations with the world right in Google’s search results. It’s called +1—the digital shorthand for “this is pretty cool.” To recommend something, all you have to do is click +1 on a webpage or ad you find useful. These +1’s will then start appearing in Google’s search results.
Say, for example, you’re planning a winter trip to Tahoe, Calif. When you do a search, you may now see a +1 from your slalom-skiing aunt next to the result for a lodge in the area. Or if you’re looking for a new pasta recipe, we’ll show you +1’s from your culinary genius college roommate. And even if none of your friends are baristas or caffeine addicts, we may still show you how many people across the web have +1’d your local coffee shop.
So how do we know which +1’s to show you? Like social search, we use many signals to identify the most useful recommendations, including things like the people you are already connected to through Google (your chat buddies and contacts, for example). Soon we may also incorporate other signals, such as your connections on sites like Twitter, to ensure your recommendations are as relevant as possible. If you want to know who you're connected to, and how, visit the “Social Circle and Content” section of the Google Dashboard.
You need a profile (so need to be logged in, I guess) to be able to use this feature.
I am intrigued, although I'm not reallllly connected to that many people via the "Google network" so not sure how well it'll work.
Edit: Also just saw it's also going to be rolled out to websites
, so it's basically their answer to the Facebook 'Like' button. Guess that's going on the TODO!
