I quite like reading people like those on G+ without all the noise and distractions on Facebook and Twitter.

Not that it ever had the popularity it needed to be really useful, but I did use it to reach out to my programmer friends. As a kind of minimal effort blog. The biggest advantage with G+, as I used it, was that I could post technical stuff (like I would on Twitter) without confusing my other friends (like I would on Facebook) and it would actually be read (unlike Twitter).
Could you not do the same thing with Facebook now that it has "Audiences"? I have a "Gamer Friends" one where I could post about DOOM or Overwatch and not weird out "normal" people
Not that I post there as we use Telegram.. but in theory I could
Neither Twitter nor G+ have the ubiquity serve Facebook's purpose of collecting every random person you know. I keep up with the people I actually care about in real life, so personally find G+ and Twitter useful on a daily basis, and Facebook as a once a month supplemental sort of thing.
The way I use G+ is mostly as a source of more in-depth information compared to the breaking news nature of Twitter.
I also have a G+ Collection for posting high quality online articles, essentially my personal version of longreads.com.
To be fair to Google it had to unify the sign in process instead of internal walls between YouTube, GMail and etc..
Do you also NOT use YouTube since that was where you were forced to use a new sign in.
Of course - any company can do whatever they want, some actions will result in people hating their products. And forcing google+ was one of those actions.
Today, my only involvement in G+ is as an administrator for a handful of communities (mostly relating to the fandoms of 60s and 70s countercultural figures -- one of a handful of subjects where, like tech, the G+ communities are more active and have a better signal to noise ratio than FB).
I think Google Photos call it "Share to social media" but they give you a link when you do that
I don't. I actually forgot about it until this question was raised, and I couldn't tell you the last time I visited it.
It is what it is.
I accidentally created a profile years ago, when it became a part of Google Apps. I took one look round and haven't used it since.
It felt like work to use, and seemed like it was built for Google's needs to counter Facebook and collect joined up data on its users rather than a compelling platform for its own sake.
I am pretty sure Google will phase out G+ in a year or two. Like Allo and Duo, they will bring something new.
One ex-colleague of mine whom I was connected with at FB left that site and is only available on G+, and in anger I "unfriended" another ex-colleague on FB whom I'm still connected with on G+, and there is no way I'm going to send a friend request on FB (I've only ever sent a single one myself). That's because I think my anger was justified. Don't send me friend requests if you then basically tell me you don't like what I'm writing. I was not angry enough to sever the connection on G+ too, however.
Since I only use FB as a "bookmark service" where I post links to stuff I want to remember myself ("sciency" stuff mostly, zero politics or personal information) it does not really matter much to me.
Very few connections on either website (FB or G+) post much that I'm actually interested in, which is pretty limited: Anything posted that's not a science or engineering topic (and nothing superficial from the mass media, please) is just noise. I don't know those people well enough to care about their private lives - when I do care I would not use FB to exchange such news.
G+ is certainly something I'll browse if I'm bored, which is probably couple of times a month. It's replaced StumbleUpon (from years ago) for me.
(Most of my connections there are tech oriented so sometimes I post a one-off thing that I found interesting)
(Don't use any other network either.)
