As a shareholder of Google, it's encouraging for me to see that Google shuts down products that didn't work out really really fast (Nexus Q and now Google+ Games).
Yeah, it's just one anecdote, and there are all sorts of possible reasons, but it definitely appears that G+ has it's niche in some regards. It might not ever displace Facebook as the main 'generic' social network, but it's no tumbleweed filled wasteland like some people would lead one to believe.
Maybe G+ Games would have been good if Google had listened to the right people, but we don't know that, eh?
I know that I'm probably reading too much into some of your Google posts, but they make me sad. I hope you manage to find something (peace? comfort?) and move on. Like I say, I'm probably mis-reading your posts and maybe I'm talking nonsense.
