I think your first reference is generally correct. Email the protocol is mostly not broken, and the most fruitful improvements to email are in the client, not the protocol. An RFC can be improved (and most have), but that should be a matter of tweaking, not replacement. I would like to see an additional kind of email built on RSS or something like it. I only get your "r-mail" if I both subscribe and poll. Maybe that can be had right now with better/different rss clients, and make (virtual) rss servers more available at an individual level. The benefit is that I only get what I want, when I want it. Although a roughly similar result can be had through email whitelisting.
