It has been said that Google has been working on a creating a social network type product. The inception of this product is called +1. Well from what I have been seeing and reading Google maybe testing a toolbar that is directly related to this product.
So far here is what I got from the breakdown the new toolbar shows your name and shows your gmail account and gives you the normal option to sign out of your account. Then you have your usually settings menu and normal search setting and account settings. So nothing too special to speak about at the moment but Google did release a statement on the new bar. ?Last week we tested a new top navigation bar, which increases consistency across most of Google?s properties and is a visual update over the previous top navigation bar. We are now rolling this new bar out widely.?
So the Google word is this is just a visual upgrade but some inside sources that have seen this +1 product have stated it looks a lot like +1 and this could be a step in a gradual process to get some buzz going.
