It's all personal taste but Discord is a lot more then just a chat channel. I tend to agree it moves fast myself. But I enjoy Discord for many different reasons:
- With a small group (like 5-6 of my gaming online friends or a small guild) it is perfect for having conversations, discussing games, or just chat. It is a more organic conversation and like a real conversation with other people you can't expect to jump in and out and then be able to follow. Its organic for those participating as long as it isn't too large, then just as in real life, it becomes to hard to follow. But small groups its great. For large servers you need to be more mindful of letting people speak and break things into different channels.
- Super easy to stream games. The other night my friend from Germany wanted to see the character creator for BG3. In just 5 seconds and a few clicks we were connected over voice chat and I was streaming my BG3 game to her discord window. She watched and commented as I went through the steps.
I have done this with a few friends. They want to show me a settlement they built in FO4. Someone else is building a house in SIMS4 and wants feedback on a few things. A friend asks to see how some ENB settings work in Skyrim so I stream my game and show them live. Etc. It is a great tool for streaming most anything on your PC
- Super easy to toss in songs, images, ZIP files, text files, etc., while having discussions or simply to share mods, documents, etc. Easy to PIN items to various channels for tracking and sharing.
- Great way to stay in touch with people using the voice chat to talk while doing whatever on the PC or even just to talk while at home.
Could go on but if people only see discord as a simple chat editor they are really missing out on so many of its features.
EDIT: One downside, of course, is you need active people engaging in things. I have a channel with just a few friends but we use it differently. We also know when others are around so we don't expect constant chatter or interaction. Its more like a tavern or pub where we gather and check in now and then.
But chat is more dynamic so it doesn't work as well if someone says something then you wait 4 hours for someone else to reply. A forum works better for that content.
