Here is a list of reasons why I like Discord more than Slack (no particular order):

- "Mark As Read" to an entire server
- Clear visibility of who is admin or not (if the Admins want)
- The ability to see sub-roles
- Can jump into a group voice chat that's always there

- Can do group video as well
- Can live stream to the entire discord, multiple people can live stream in the same discord
- Nitro users can carry emojis from one server to the next.
- Very little onboarding friction (can be an easy one-click URL)

- Ability to search for discord servers, everything in Slack is like..silo'd out
- Actually performant
- Free, with perks if community members want to "boost" server
- Can add friends from different servers, easier to stay in touch

The only thing I want so so so badly is threaded discussions. With growing communities, not having the ability to thread makes you feel like you're polluting the chat.

Feel free to add more things!
