The debacle that was Google Wave into Google Plus is... really hard to really come to terms with. I don't even know that Hubris is enough to explain how badly managed that time period was by them. Just so bad.
Wave was an interesting jumble of ideas that just didn’t bring a coherent answer for why anyone should use it. Google Plus was 100% hubris. “If we build our version of Facebook, it course everyone will flock to it.”
Firstly, that whole account-unification thing where YouTube accounts were getting merged with Google[+] logins. That rubbed me the wrong way.
Then the Google+ promotional stuff all talked about how you could use "Circles" to silo posts to different "circles" of friends. It sounded very complicated and I was worried that I'd publish something snarky to the wrong group of friends :)
I wonder how many others had the same concern? Given that Steve Yegge accidentally published one of his rants to the public that was meant purely for internal Google consumption (I think that was on G+ ...?) that might have been a legit thing to be wary of.
There was also the very minor annoyance of G+ taking over the + operator in Google search (previously you could say +keyword instead of "keyword" to force literal search), but I don't think that would have swayed me against joining.
