In previous years, I've invited undergrads to post to Tw*tter during my class sessions, as an alternate way to participate & as a shared (public) backchannel adding extra digital materials to our conversations.
This year, for obvious reasons, that's impossible, so I'm asking them to do so via Mastodon (which none of my students have used before).
It'll be a little experiement. Let's see whether #SOCccc23 gets any use from my #copyright students.
