Another aspect of this topic -which we could talk more about- is G's strategies to up the battle for the social audience. I think they are committed to this as perhaps the biggest factor for audience and the revenue streams that come with it for the near future; say, 2-3 years out... or even a little longer.
As a webmaster, I'm thinking about how can I take advantage of G's focus in this war to help my little business? I wouldn't fret about how +1 and stuff like the author tag works or looks... that's not, IMHO, important.
