"+1 Is an abbreviation for digital 'is pretty cool', to recommend, you need to do is click +1 on the web page or ad that you think are useful. +1 Will start appearing in Google search results"
So can be interpreted, the more people are recommending, then google will look at both those pages. That will facilitate the netter to get accurate information.
Perhaps this feature is one way to improve the quality of search results from Google that has been dominated by the AGC (Auto Generated Content)
Although already recommended since March, google plus one is still not completely perfect. +1 Additional user recommendations result do not appear, wait several minutes before the new value of +1 can be increased. In google Indonesia (google.co.id), plus this one has not emerged, and the javascript from google apis I think is still slow and heavy, still less rapidly with like facebook.
