Discord for gaming ramblings and chitchat may be okay, but I hate when software projects misuse it as a support channel.
Give me some forum instead, I know many ppl here on HN dislike discourse, I don't get it though, for me it's a great way to do a forum in a modern way. Can't perceive any UX issues with it (I do know the arguments, I just think they are not true, or much less of a hassle than claimed).
Maybe we need something like discord, but it should have a way to group a question and the following conversation including asking back and answers, and send that to a website where it appears like a forum thread. Basically just select it with mouse, right-click, pick some option, select some keywords for taxonomy and good to go. Should be 5 seconds of work after the person with the problem is satisfied. Yea that is something I would not hate I guess.
