Email could work like this. Threading emails in a chronological list is just a trend in clients. There’s no reason clients couldn’t do it like this, or display emails like IM software threaded by author and sorted by last message (I’ve been searching my entire life for an email client to thread IM-style).

Outlook breaks e-mail threading. It's really quite annoying. Forget "e-mail clients could do this" most e-mail clients written prior to 2000 did do this, and many after do as well.

I think part of the point of TFA is that the fact that you don't control if other people top-post or use crummy clients means you, in practice, can't get this with e-mail, even though you theoretically could.
