chats are fine. the real problem is facebook groups that replaced traditional forums. i mean, it's essentially just a simplified discussion board designed around "the flow", and as thus, is no way to share and distribute information, especially since you can't really navigate it in a way to find the right answer. so every day it's the same five questions asked over and over again, and with facebooks rules on trade for non-corporate entities, it's essentially killing some hobby industries. though, you're right in that a lot of people have also moved to discord as some kind of forum replacement, and it's even worse for the purpose of information distribution.

not that reddit or lemmy are any better. i mean, they suffer the same problem due to the way information is meant to work on them, yet people use them as forum replacements.

basically, the real problem is that people have abandoned traditional forums and use these convenient platforms as replacements. but it loses a lot of functionality along the way. and it's a sacrifice that most people just don't care about due to the convenience.
