I'm voting Google + from now on. Why?
Google has started to integrate your social media friends into your search results. It's called Search Plus Your World. http://googleblog.blogspot.com/2012/01/search-plus...
When you search Google and your friends on have shared or liked that subject it will pop up first, like referrals.
Right now they are showing results for any share but who do you think they will phase out first or at least place less clout on? Their arch enemy Facebook. IMHO.
If you are a blogger or even a hubber with social friends you will want to be sure to check out Google + so when you share a hub or post your circles see it.
