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.
I feel (rightly & legitimately) called out 😭 I literally got two months into my renaissance political intrigue campaign before I discovered Court of Blades. It's a perfect fit for my interests, but now my campaign is lousy with so many d&d tropes (Tieflings! Dhampirs! Changelings! Dragons!) that I more than likely couldn't switch systems without home brewing everything out the wazoo 😓
I'm a big fan of @slyflourish@ttrpg.network's trick of preparing secrets, clues, or general plot point revelations in advance and without anticipating the context of where or how they will be revealed. That is, you just prepare a list of ten facts or details that will engage the players if and when they learn them, and you improvise how they learn them at the table. It's great for when a player character unexpectedly goes to the library to aimlessly look for clues, or the PCs start talking with an NPC and you need to drop some nugget of info to make the conversation feel worthwhile.
I was a bit bummed to see that Mike didn't mention any of the Fediverse options but honestly Lemmy and kbin are still cooking as technologies so I don't exactly fault him. I was surprised to hear him skeptical of Patreon—the same incentives are there, surely, but I wasn't aware of any recent actions they had taken.
Replacing Discord will definitely be painful if/when it comes.
I'm a big fan of a small app called UpNote. It's clean and simple with a few power features you can use if you really dig into it. It largely has the same baseline set of features as Obsidian, but it supports syncing across devices out of the box and has a one-time purchase of a lifetime membership.
