I’ll give you an example of why nobody visits Google+ any more.
This is my Google+ homepage that I just checked for the first time in a week. The top story in my feed is by someone I don’t even follow. In fact, that’s the dominant content above the fold. In other words, I have to scroll down to see any content I might even care about.
There’s also a YouTube widget stuck on the side for no reason whatsoever.
