I wonder about that “#2 social network” statistic. Google is, e.g. getting increasingly pushy about getting me to merge my YouTube account with my G+ account. I wouldn’t be surprised if a sizable proportion of whatever metrics went into determining that #2 ranking were derived from people who did NOT think of themselves as “being active on G+”. Of course the same is true for Facebook, to some extent, with an increasing number of web sites outsourcing their comment system to them.
