"+Mark Traphagen Not 100% sure yet? Just tracking a few search phrases to see who lands at the top of the G+ SERPs organically and then filter for Best of and then like you mentioned, I visit their about page to inspect description/narrative and compare. Very non-SEOmoz scientific but have uncovered a few "OK I get it" routines that may be useful in the not too distant future."
"+Neil Ferree Are these logged in to Google or non-logged in results? Of course logging in will make everyone's results for a search different (personalization), but because of your post I checked non-logged-in (results a new user or someone checking out G+ is most likely to see) and found that I am indeed #4 for "content marketing," and also #1 for "social media consulting" and #16 for "social media marketing" - all keywords I have on my profile page."
