I think my reasoning for not doing it thus far is because.. I much prefer traditional forums. But I do understand if there are a lot of people out there who want the quick feedback a Discord is able to give. Especially before registering on Itch and buying the app.
Yup! I had Patreon integration all set up and ready to go with a Discord server, but I had to pull back on it all due to mentioned personal reasons in previous dev logs. Things are looking better recently, so I'll probably consider some sort of Patreon benefit and open that up sooner or later.
