> Discord is easy to use which is why its so popular.
I found this phrasing subjective because I don't find it easier to use. I tried Discord Web, Desktop & mobile, frankly they are not easier to use for me. I found it confusing because I suddenly need to have a role assigned to me. For that, I have to go through loops and hopping on subchannels to get myself a role for me to be able to have a conversation. One server that have like 5 different subchannel and I have to go through each of them to get a role. After trying to get figure out how to get that for half hour, I gave up. Simply too much work for trying to ask for a help. Discord is not designed AND substitution for general forums. I seen several game developers/publishers trying to tell their Steam users to go on Discord for any issues, requests, anything. I found that convoluted because Discord is not easier to use for first timer and plus there is Steam forum for this.
One thing I can't do in Discord (Slack & Signal included as well) is that I can't have multiple chat windows in my desktop like we can do in Trillan, Pidgin, AIM, ICQ, etc. My work is using Slack and it is a pain in the ass to go back and forth with various channel than having multiple windows for easier access. I prefer Slack over Discord because Slack don't make it complicated when it come to channels.
