I Implemented the +1 the day it was released on one of my sites. I gave it priority positioning over the facebook like. The google +1 now has about 120 votes and fb like gets about 200-300 likes per day.
So about 3-5 +1's every day vs 200+ likes per day.
Also, No other site in this industry has implemented +1 and there has been no ranking increase as of yet.
To make it clear, this +1 serves 0 purpose as of right now, and if it does not positively effect rankings at all I will be removing it. I feel that many webmasters also feel the same way.
The like button even if it does not help with rankings, is actually seen by their friends and generates traffic and buzz.
