I think it could be a success, I mean it's google we're talking about... same guys that own youtube, adsense, adwords... the best in their fields.
I think they've launched their +1 button a little too late... they are no more pioneers... google should abandon social networking functionalities and focus on what they obviously can do : search engines...
Hello At the same time may be this will not affect but after some time and having some more 1+ you will get the benefit.
It may or may not be a success, but one thing is certain, it will certainly curtail the number of sites simply creating bad content to rank well
True is that I don't know anything about that. I saw +1 only today and whenever I make search signing in to google.
