I don't think what a "normal" person has done on Facebook over the past 5 years is a fair comparison. Facebook didn't even have a public "subscribe/follow" concept til last week, whereas Google+ launched with one. Also, these aren't normal people, they're the leaders/overseers of the company using (or not) a landmark initiative whose leader (Vic Gundotra) clearly thinks that ideally it'd be used for both your private and public interactions. At the very least, it'd look a lot better if they had accounts, tried making a public post (even just to congratulate the team publicly), and looked engaged.
