Depends what you use it for, there's some great servers for a lot of things. I don't really care about platforms and basically use them all. Certain people really hate Discord but the alternatives don't have many interesting things on them, and the people who use them aren't a very diverse group. Checking all the right FOSS and feature boxes is nice but it's not what actually makes a platform good to use.

How to make a discord account? I get so many captchas and would have to enter a phone number but all the free ones online don't work.
