It was worse than that: they forced _everyone_ into it, whether or not you had any interest in using it.

They did this before having notification control or usable filtering[1] so what this meant was for most of year, you'd login to Gmail and see the upper right notification badge be !!!LOOK AT ME!!! red only to click on it and see it was telling you that some dude who no-showed on a Craigslist sale 10 years ago in a different city had been forced to “join” Google+. Even worse, it took like 6 months for their iOS developers to give you any control over push notifications so you got all of that as push notifications until you deleted the app.

They also annoyed key communities like Google Reader users: that wasn't their largest popular social network but it was one which people actually liked and it disproportionately skewed towards people like journalists, bloggers, etc. who recommended technology to other people. The conversion to Google+ was really clumsy and they did things like replacing the popular Reader commenting system with a Google+ “integration” which didn't work at all on mobile devices[2], which meant that a ton of influential people had a really negative experience and told everyone they knew about it.

1. The “circles” idea reportedly worked well when it was Google employees using it internally but it relied on the poster picking an audience for a post, which failed in the real world when the spammiest people think everyone is interested in their every word.

2. The dialog was sized for a desktop display so the post button was inaccessible off the screen.
