Needless to say, this will make it even harder to get repeat visitors to your site because how many of us really use the +1 for sites we visit? In the past, we could count on being on the first page for users that came to our site before. Users didn't have to do anything to come across the same site.
As a test, I googled and visited one of my sites suffering from this. Even after several visits, it still didn't show on the first page of google's results. I then clicked on the +1 and performed the same search. Pow!! It showed on the first page of results!
Who else thinks this is wrong?!?!
