Many posts over the years related to this where there are some mentions lamenting the old forum days and the value of those independent platforms and the way they organize and provide archived history of your project/your community. Discord, a realtime chat platform, still isn't that right?
The reasons ppl moved away from forums weren't entirely legit - the gaming community origin as a fast paced attn-deficit platform for rapid meme sharing, the rapid switch to mobile-first mentality needing UIs to match, a gap in generations of users not used to the forum posting / email like UX etc..... but I mean, look where we are right now here on HN, a classic forum by most standards, and even what Reddit is, a platform of a million forums,... The forum still holds a lot of merit no? It's just been pushed down under the weight of the rush to popularity and the mentioned issues.
