So you want to go back to mailing list and run your own email server?

Maybe time for a Usenet renaissance?

No, we’d like to go back to the culture that created protocols to solve our needs, such that people could create interoperable servers and clients to implement those protocols.

Email is an open protocol, perfectly suited for delivering messages between people. Discord is a closed application, unsearchable, any server or account may be nuked at discord's discretion, thus it's entirely unsuited to replace e.g. a forum.

You do understand the difference?
