Right! To that let's also add we have a bunch of smaller communities within our
OpenStack big tent. Each one of these teams might requires a different approach.

This is a good point and I believe it may explode into several smaller
discussions. I'll try to light the bomb:
- We used to be a community that assumed good faith about people, proposals,
etc. Have I been genuine enough to believe this is still true? I certainly
work under this *assumption* unless I things stink really bad and even then,
I'd try to work around the issue without unecessary finger-pointing.
- We've always been a multi-cultural community company-wise, tz-wise,
culturally-wise, language-wise, etc. These is super hard to coordinate and
finding a right solution for everyone is even harder. For example, depending
the communication medium you might have a bad/good impact on non-native
English speakers. Spending enough time understanding people's perspective is
critical to avoid the frustration of non-native English speakers. Asking dumb
questions that translate to "I don't get your English" when things are utterly
clear doesn't help, really.
- Is picking the communication tool based on people's preferences rather than
based on the technical issue they are meant to solve the right thing to do?
I'm sorry if this is missing part of your point but I believe each one of the
tools we have are meant to ease specific communication issues for specific
cases. That is to say, I agree not all mediums are equivalent but I do think
there must be a preferred medium for "whenever you don't know where to send
$X". To me, that's the ML.

Ok, let me see if I can put this in a way it doesn't sound bad. Bear with me.
Sometimes, when it comes to keeping communications healthy/going in
multi-cultural communities, it's better to have a bit of "assumption". Depending
on the problem's space, topic, etc, it might be healthier to assume some things
on specific points than keep poking with the same questions (structured
differently) which just end up frustrating folks. I guess my point is, there's a
time and space for every discussion/question. Unfortunately, I believe we don't
spend enough time understanding this and we as well sometimes disagree on what's
the right time/space to discuss things.
Hope the above makes (some) sense. As a general thing, I prefer to assume good
faith, it truly makes my life simpler.

This! This! and again, THIS!
