It's just longform twitter really, so can be short fiction, essays, poems, actually even podcasts and whatnot. I suppose it's a nice away from twitter, I probably only really check in in twitter for a handful of people and I'm mostly interested in their sporadic longer form essays, their tweets are somewhat garnish but I can easily do without. In general there is maybe a move away from microblogging(?)

What's the deal with the royal society? 🤔
