Follow-up: turns out I can't DM because you aren't following. (I'm a media critic and media literacy educator, but no pressure to follow -- everyone should curate their feeds as tightly as they prefer.) If you'd like, either follow and I'll DM, or let me know where I should email you.

Ok, I'll DM a little later. (Preview: a lot of variations on unspoken rules of engagement, especially how to not gum up the works so much that someone inevitably screams "GTFOH!" at you.)
