While I've seen the usual batch of tech early adopters, I've also seen a large number of high school and college friends that are not in tech who have accounts and are using them. Granted, it's nowhere near the facebook level of penetration but my actual interactions with friends on it have been of higher quality (I barely use facebook so that may have a strongly confounding effect on my results), largely because I can control who different types of content goes to. I think the pervasiveness of G+ is going to go a long way in continuing to drive adoption and use. Facebook feels like a place I go to waste time, while G+ is always there when I'm inside of anything google (and between gmail, calendar and search that's at least once or twice an hour).
