Have you seen Google’s “Dear Sophie” video? Apart from it being adorable, you also get a peek of something we can only assume is soon to come.
If you look closely, you’ll see a little Google +1 extension within the Chrome extensions toolbar. Assumedly, this would allow you to +1 any site you visit, which of course, is Google’s aim at social search. Of course, if Google is relying on Chrome to mainstream this tool, that’s not going to do it. A Chrome extension would simply be a convenience piece for those who have bought into it, utilizing sites who haven’t. And letting the world know you approve of this site, within Google search rankings and more.
