Google has introduced the plus one (+1) button – which is basically a “Like” button for search results now and will also soon become a sort of voting mechanism from web sites to add to the “Iconistan” confusion across the web. (Kinda cryptic isn’t it Google?)
I prefer the AddThis widget used above). So now when you want your friends and “connections” to see how you feel about a service, site or story – you’ll be able to click the +1 button to share that preference with your buddies and family in their search results. It also tells Google about all your likes and preferences and will very likely lead to influencing the search results if it gets wide adoption.
