Imagine if, instead of simply shutting down Reader, Google had gradually and subtly integrated it more and more in to Google+ over time. Things could have turned out very different!
Imagine of Google+ had had a proper API for automatic posting. If I remeber right, there still wasn't one when Pages dropped.
So unlike Twitter and Facebook, I couldn't just set up my Wordpress site to feed all my posts to Google Plus. I had to go and manually post them.
They also had the real names policy still, so I have to post as my real name instead of the name I post online with everywhere else.
Plus was so poorly mishandled because Google does not understand people at all. You can't boul everyone down to a handful of easy categories to make it easier for alogrythms to manage.
