This idea of using +1s as a ranking factor is terribly flawed. This is because websites that support majority views on controversial political and social issues will naturally get more +1s than sites that support minority views (Obviously so, since the majority outnumbers the minority.) This means that Google would effectively always be promoting the majority view by sending more traffic to sites that promote it, which would then further increase its dominance, and so own. The whole idea is terribly flawed.
