That said, the perfect is the enemy of the good.
While I agree with that statement in general, I couldn't quite make out what you meant by it in this context.
Are you saying "good" = "most of the times your Google messages will go to the intended recipients" and "perfect" = "all of the times your messages will go to the intended recipients"?
Nobody is talking about that this is some acceptable status quo. It's a bug and it will be fixed. If past performance is considered, it will be fixed fast.
You are reducing what happened today to a mere "bug", which is the way Google (or developers) would look at it. Instead, approach it from the user's POV. Having your financial, personal, professional, secret or illegal (yes, I'm sure there will be that too) communications sent to multiple random people is more than just a bug.
I agree GTalk is "really, really good" like you say, but then what happened today also should "never, ever happen".
- Multiple sign-ins cause issues all the time (Gtalk in GMail, GTalk on the phone/tablet is already enough to cause it to go nuts and send messages here or there, seemingly random). It _could_ allow me to specify what I prefer (XMPP should support that), but it doesn't.
- Loses messages all the time (every ~10th message doesn't arrive. My wife and me stopped using it for anything of value because of this)
- Hangout. The "We don't like XMPP anymore, want to force you to use G+ and .. have the most ugly show-me-some-comic-bubbles interface to make the transition extra smooth" app
Actually I wouldn't be surprised if the issue is hangout, not GTalk-the-original-xmpp-thing.
Yep, that is what they say. You know what else they say ?
"The enemy of good is good enough"
and also
"A witty saying proves nothing".
