The "" feature on the Android Market is intended to be a more personalized complement to the standard star-based app-rating system that users have traditionally employed to give their opinions on applications.

BACKGROUND:

The premise is simple: If you like a particular application on the Android Market, you can sign into your Google account and give it a +1 that all of your other Google contacts will be able to see when they click on the app. In other words, you'll be able to see whether or not your friends and acquaintances are fans of a particular game just by clicking to see if any people you know have recommended it. Friends' and contacts' +1 ratings will also appear in search results if they have recommended any products or websites relating to the search keywords, Google says.

"With a single click you can recommend that raincoat, news article or favorite sci-fi movie to friends, contacts and the rest of the world," on its official blog. "The next time your connections search, they could see your +1's directly in their search results, helping them find your recommendations when they're most useful."

Google began rolling out its +1 feature on its Web search results this past March, letting users give recommendations on whether various search results accurately matched the keywords they entered into the search engine. Google says that it's going to start implementing the +1 system on other popular Google properties including Blogger, Product Search and YouTube as well. Google is also working to integrate the +1 button onto a wide variety of partner sites, including Rotten Tomatoes, The Huffington Post, Best Buy and Bloomberg.
