> It's Slack for friends. Discord basically does everything Slack does (rich-media real time chat with a specific group of contacts.) It's far easier to crank out a new discord for your friends and you don't get slammed with the "Free Organization" restrictions that come with Slack.

This is what I often point to in Discord's favor. Slack's business model is at the "team"/"group" level and makes the most sense for organizations with a strong cohesive identity over time, whereas Discord's business model is at the individual user level and allows for a lot more ephemeral friend groups to flow in/out of "servers" (teams/groups/what have you) as makes sense to them.
