John Battelle writes in his blog:
"Given that Google+ results are dominating so many SERPs these days, Google is clearly leveraging its power in search to build up Google+.

...“Google has decided that beating Facebook is worth selling their soul.”
"...If a large percentage of people are logged into Google and/or Google+ when they are searching for stuff, ...Google+ pages are going to rank well for those people.
Hence, I really have no choice but to play Google’s game, and tend to my Google+ page, be I a brand, a person, a small business…. are you getting the picture here?
If you decide to NOT play on Google+, you will, in essence, be devalued in Google search, at least for the percentage of people who are logged in whilst using Google."
