Sure, but I just use a personal Telegram channel for this. It's quite well-searchable too, and it serves me 95% perfectly.
I can also write my own plugin bots to respond to specific queries.
I considered Discord but I hate its UI, especially every time I go to the website it wants to do a phone verification. F that, I'm out. If you are a nonessential "fun" app you need to be as low friction as possible.
Plus there are scripts to back up the said channels. With Discord I haven't checked (but maybe there are as well).
So mostly (1) Telegram is still snappier and (2) Telegram was there first, more or less, at least on my own timeline of checking chat clients.
