Today is the day you will be able to +1 some of your favorite websites. The feature lets any website add a +1 button to its site so readers can like any content they enjoy. Not only does this allow you to ‘like’ your favorite content for others to see but this also helps websites with traffic, ad value, etc.
So how does it work exactly when a bunch of your friends +1 their favorite material? The next time you search for something on Google, it will incorporate your friends opinions and beliefs in your web searches.
