I'm guessing you don't interact with the development community very much then? Almost every open source project I encounter at least has a Discord server, it's the new easier and more accessible version of "find me on IRC", but most that are less than 10 years old that I've encountered also don't have a forum and direct you to the Discord for even the most basic info. In fact I've had multiple popular GitHub repos that directed me in an Issue I was offering to file a PR for to go check Discord for an explanation of how the project was even used.
