I am a big fan of Google, but their +1 initiative will not take off I am afraid. I gather it seems to be similat to the facebook Like button, but the latter button helps you see what your friends from the social networks likes, while it will be harder for Google. In the presentation about +1 they say you will be able to see when friends and family +1 something, or people clicked on a site +1 button, but how either way has less meaning than the Like button from Facebook. And even though we all use “Google” as a verb, I hightly doubt the company will be able to use +1 as a verb. I much prefered their Google Wave project, which I am still kind of sad they discountinued, although it is on a life on its own in the Apache project.
