Search giant Google is trying to push into the market for social networks.
After the launch of “social search results”, people in the near future can recommend results to others instantly with a feature called “+1” that is similar in purpose to the Facebook “Like” button.
The +1 button is shorthand for “this is pretty cool” or “you should check this out.” Click +1 to publicly give something your stamp of approval. Your +1’s can help friends, contacts, and others on the web find the best stuff when they search.
When you +1 something, your name becomes associated with that link “in search, on ads, and across the web,” according to Google. It also shows up in a feed on your Google Profile, which is required to use the product.
Your +1’s are stored in a new tab on your Google profile. You can show your +1’s tab to the world, or keep it private and just use it to personally manage the ever-expanding record of things you love around the web.
