The +1 button isn't getting any use in serps for me, nobody clicks on it from there before seeing my pages, but it sure looks pretty.
Anyway, I'm not going to create a profile for myself, ever, but is publishing a page for my site allowed ?
I want traffic from Google, not a platform to play on where the cost is my privacy, because who knows what I'll want the world to know 20 years from now and the internet doesn't have an 'un-publish' button. (I put my foot in it enough on these forums! :)
