When Google+ was new, I liked the idea of the inherent control ostensibly provided by its “circles.” I left after a bit. And at some point, Google tricked me into signing back up without my noticing. Truly. When I noticed, I left again.
Now I want to follow Linus Torvalds’s posts, for personal interest. So I’m signing back up today.
9 April 2017 Update: I never went back. So I’m out of G+ again. It was a hassle to find where to unsubscribe, but I poked around and found it after a bit.
