I spent years, but I didn’t find any interesting acquaintances, and I came across such people that I thought I was in the Stone Age, I seemed to be dumb by 25 percent at least when I communicated in discord or I was terribly bored, it’s difficult to explain, but that’s about how I can describe my experience.
I use Discord because of network effect (i.e. that’s what people use, so I’m sort of stuck with it).
I refuse to install the app on my devices though. For PC, I use the web-based version. For mobile, I use Matrix bridging. The bridging only works for messaging, not voice/video, but I don’t need that on my phone.
