Google announced yesterday that they will soon be launching their +1 service inside of Google's search results, which will function as a sort of recommendation from one user to another regarding what search results a user found best, somewhat similar to the Facebook 'like' or Twitter's "retweet." The service is destined to make it's debut on the desktop version of Google Search in a few weeks on Google.com first, and will slowly roll out from there.
Users will only see +1's from individuals that are already known and important to them, such as chat buddies or contacts. The recommendations will appear in Google Search results, but also in other Google products and sites as well. Users will be able to manage all of their +1's from their account.
To take part in +1, users will need to have a Google profile, or if a user already has a Google profile, add the +1 service to it. Althought the service is yet to launch, there will soon be an experimental search site that users can try out.
Check out the video below from Google to see their explanation of +1:
It is not clear when or even if +1 will be coming to Android devices, but I am betting that we will see this feature appear in some form on Android devices by the end of the year. Head over to the official +1 page for more info on the upcoming service.
