At the same time, the minimalism pervaded the rest of the platform. Instead of giving its users reason to spend time on G+, the site seemed to expect for people to entertain themselves. As such, there was little that drove more activity, connected people, and gave reason to spend time to understand all the features.
One thing I misremembered. There was a serious issue with marketing. They didn't open up to the public for several months. By that time a lot of the hype died down.
If Google had pivoted 180 degrees and offered up a full featured social network with pseudonyms and, like, one other twist so that it wasn't just Myspace, then there's a reason to care about Google+. LinkedIn is facebook for professional identity... There have to be other identities not shown on Facebook that google could have gone after.
So when I got to joining what did it present? Welcome - connect to some famous people. Now add your friends. Not one mention of interests, and I'm not sure they even mentioned circles. So everyone joining was being presented a picture of Facebook.
I didn't last long.
But there was simply not much to do, contrary to what you'd expect with all the other Google services available.
I was still very high on Facebook kool aid at that time. It may have had a bad rep to some people, but this sentiment was years away from reaching people like me.
Note that I am about as much of a Facebook insider as possible without actually having worked there. I personally know most of their top execs, Zuck interviewed me in 2007, turned down a PM offer to join Bebo but stayed close with a number of them for years. I would have loved to be filthy rich with those options, but if I had joined I would feel guilty for the destruction I contributed to.
I do agree that there was a missed opportunity to integrate their other awesome products you mentioned. But to me even with those integrated Google+ would have needed a raison d’etre that was substantially different than facebook.
