Discord has much better performance for large communities, and I've found it to be perfect for remote collaboration with its intuitive and super low friction voice channels.

But the issue around professionalism that you bring up is certainly valid. I don't want to have to maintain separate accounts for work vs play (unless there's a seamless way to switch between them, like for Google, but currently there isn't), but currently there's no way to present different personas to different communities from the same account. Some examples:

- Can't change avatar based on server: https://support.discordapp.com/hc/en-us/community/posts/3600...

- Real account name shows up on profile even if you provide a different nickname to the server: https://support.discordapp.com/hc/en-us/articles/219070107-S...

I think they're still super laser focused on their core demographic of gamers rather than trying to expand into professional use and compete with the likes of Slack. You can certainly still use it in a professional capacity and it generally works great, and is better than Slack in some areas, but the lack of effort put into catering to those use cases definitely shows.

FWIW, I currently work around the issues around multi-account management using Firefox's excellent containers feature (using 1 work container to segregate all of my work accounts from personal ones without also having separate views of history).
