These are all good questions which deserve proper answers.
From my perspective, we're currently flat out in the early alpha stages (non-feature-complete, known and unknown bugs) and all trying frantically to keep up with the daily leaps in functionality, features supported etc.
Therefore, I/we can't give you many good answers just yet, but we will make sure to reference your post as soon as our cycles free up again.
How does that sound? I know it's not much, but it's the best we can do currently I'm afraid.
I'll let @Ikey chip in with extra decisions as priorities are ultimately his call. If he ends up contradicting me, consider what he says our official reference.
chris_debian Could you add a few words so that users know where to find documentation, and or know where to start creating it ;-) ?
FTR, we now have a Documentation tag, which we're beginning to flesh out. Read the tag description to get an idea of what the intent is.
In that section, the "How to test moss" thread has a link to our onboarding README, where curious early adopters can get started.
Otherwise, the big picture of our goals is outlined on our website.
