I find that people who complain about email volume are not only unfamiliar with setting up rules to file messages into folders, but entirely uninterested in learning how to leverage their tools that way.

In fact, it seems many of them resent having to learn anything in order to be more productive, instead insisting the burden belongs on others. “I don’t want to get all that email, so it’s OK for me to make you visit a web page several times a day to participate instead.”

And no, Discourse’s “mailing list mode” isn’t sufficient, it’s as garbage as the rest of Discourse, especially when D showed the right way to do this: Mailing list primary, NNTP newsgroup gatewayed (or vice versa), with a web forum for those who insist on one.

If only LLVM et al had gone that route.

It's replicated work for every person who wants to set up filters and notifications. Discord or whatever has defaults that don't require everyone to create their custom environment.

But you trade a lot for not wanting to set up your own custom environment. You only have to set up yours. There is no one size that fits all, and if this flexibility comes with these features mentioned (non-proprietary, federated, archivable, accessible, not dependent on a specific company), then: yes, please! How could anyone not want this?

“It sucks for everyone equally, so it’s better.”

Nah. The “replicated work” is in deciding what you want your mail folder structure to look like, which is a pretty personal decision; creating the filter on List-Id itself is trivial.

They use some kind of API to connect to forums and display them on mobile in a semi-unified UI.

There's nothing stopping anyone from creating an application that uses the same APIs and provides the contents in a more fitting format.
