I was one of the (evidently very few) users of Wave. While it had many features, the one I remember now very fondly was proper message threading. It wasn't until years later that I used my first email program (mutt, of all things) with simple, correct threading.

I'm still somewhat annoyed that major email providers don't support proper threading. I wonder why. Is it because email is supposed to be "easy" and threads are cognitively "hard"?

Yep... that's the thing that killed it... everything was constrained to a threaded chain of replies, instead of being a proper multi-user realtime editor.

It was trying to be Reddit, Slashdot, HN, etc... a threaded forum post, instead of hypertext you could markup, annotate, or edit.

Define proper threading?

It wasn't flattened like in many consumer and business targeted email readers these days. Which was a sharp contrast with Google's other main communication product, Gmail, which flattened threads into conversations.
