I glanced today at Pew’s 2015 survey on social media usage, and was a bit blown away by the big numbers, even for platforms that don’t seem to be growing.

I certainly didn’t realize that 62% of all American adults–and 72% of those who are online–use Facebook. And because I think of Facebook as kinda 2010, I was surprised that usage rates among online 18-29 year-olds are at 82%, though usage seems to have plateaued (I guess so, when they are so overwhelming).

Us Twitter users are at 23% of the adult population (and the same percentage of online adults), but not growing at present. And the boom is among users of Pinterest and Instagram, which I understand but vaguely. LinkedIn seems to be in its own little ghetto concentrated among college graduates out in the work force, especially those aged 30-49.

As usual when I read these techno-summaries, my brain hurts and I want to reach for my familiar sites and familiar platforms. But I’m still resisting The Facebook, even if I’m the last American to hold out.
