Social Shares and Social Signals are becoming more important to Google for determining Authority, so naturally social media signals and engagements are having an impact on how ones site ranks in the SERPs
90% of the time, when I post to my G+ Stream, I post to Public vs. Limited Circles. Once a post gets a few engagements, then sharing with the relevant Circles becomes more applicable.
I'm also a big fan of Scoop.it Not only coz its very easy to use once you install their bookmarklet so you can add new content to the right topic, but once your topic hits a certain point, it tends to attract more readers and followers. Not sure about the link juice that comes with this portal, but that's not my main driver anyway. What is appealing and what I opt-in to get alerts is how many times my content gets re-scooped and shared - i like when that happens.
I didn't know about this SEO data feed from Blekko - worth looking into - nice tip!
