That’s honestly the biggest potential upside with Meta’s Threads in my opinion: better chance to grab more of the big online personalities (e.g. it’s on the record that they’ve been reaching out to major celebrities) and (at least for the foreseeable future) Meta seems invested in full-featured Fediverse interoperability including account migration, etc.

The two I would recommend are both centered around GM prep:

• The Lazy Dungeon Master by Mike Shea (@slyflourish@ttrpg.network , @slyflourish@chirp.enworld.org )
• Never Unprepared by Phil Vecchione (@dnaphil@dice.camp)

I don’t think either of these are perfect, but they both offer really good, actionable advice. The philosophies/systems described in these two don’t naturally mesh, and I think that’s a plus. Every GM needs to figure out for themselves how to prepare to run a game, because the things each GM needs are unique. I think having two books outline pretty drastically different approaches can help you triangulate your own needs and methods
