I think I can share my website to someone esle and do a better SEO for it when I click "google+1" to my site. Now I don't know whether it is share to someone else or not, but now my site ranks first when I was signing in my google account and searching some of my site keyword. I need to sign out my google account to see the true rank of my keyword now. What I doubt is this: If I click google+1 to 10 sites for one keyword, does it mean the 10 sites rank top 10 of my search result?
