Google has rolled out the new +1 button in search results and for webmasters and today brings us the official +1 Chrome extension that lets you +1 any article on the web. From the release notes:
This extension let you +1 any web page. Just simple as one click!
It’s a great new addition to the Google social suite and it works seamlessly. See something you like? Hit the +1 button in Chrome and a link to that story will be created in your Google profile, making it easy to recommend stuff to the web at large. The extension lets you select a Google profile from which you are posting and enable personalization of content and ads across the web based on your and your contacts’ +1′s. This page explains the system in greater detail. While we’re at it, I just +1 this post. Your +1′s appear publicly in search and on ads as well. You can lock your +1′s on your Google profile so only you can see them. Plus (no pun intended), you can delete any +1 privately or publicly listedon your Google profile.
