Discussion Board!

[sjml]

I had a few requests to start a Discord and while I'm open to the idea, I can't really commit to being present enough there to have it be worthwhile. (I'm also concerned it would just be a ghost town...) So for now I'm just opening up the GitHub discussions to see if anything comes of it. If there seems to be enough critical mass of a community here, we can look at next steps.

(This may also just end up being a ghost town, but so are most of my repositories and it somehow feels less shameful.)
