Frankly it’s not really great even for that, but they have captured the audience and now we are stuck with it.
Every time I boot into Manjaro to do some gaming, almost always there’s a new update for Discordavailable and guess what? The updates to Manjaro are always lagging behind a few days to a week, and Discord won’t run with a slightly out of date client.
The only way to get is working is using the snap, and who doesn’t want use some 3rd party package manager just to send some kbit/s voice data?
Additionally the interface sucks and is really bloated
I don't disagree, but that does not change the fact that people have moved from sites like SO to Discord for this purpose.
There are Q&A channels, so not everything is chat, but Discord search is abysmal
Slack is another place where former SO content / answers are happening. Discourse too. The tl;dr is that it has become more fragmented, for better or worse
SO has a related problem to Reddit. Some mods high on their status and power
The move has happened because SEO rotted out The Internet to the point there’s been a “theory” that the Internet died a decade ago. If the current Internet is unsustainable under new technology trends then the new parts need to and will evolve to thrive inside the new ecosystem.
Discord is great for chatting with your friends, gaming, etc. but man it's a horrible knowledge repository.
