Personally, I think the jury is out on Google+ as a social platform...
However, the 1+ button is really a separate issue. Yes, Google will use that signal, along with other social signals in ranking. But as always, the real way to affect whether your content is shared, "plussed," or given a link is to provide content that compels people to respond in some way. More and more, quality counts.
