+1 is something very new and is still in the developmental stages as of today. Though Google is really excited about the widget, it is still to use it as a full-fledged tool in order to determine whether or not to include the same in the ranking algorithms.

+1 button is really good to get rank on top of the Google as now Google search engine considering as a ranking factor if you got higher +1 votes.

I would like to ask one doubt at this moment is this +1 button going to affect the SERP's?
