What i find interesting about this article is not the realization that MPI is like email, but the reverse, that human collaboration using messages is like MPI. The suggestion to use SMTP as a transport for things much more complex than emails is something worth looking at. It relates to my belief that the instant messaging difference does not come from the new protocols like XMPP for jabber, but from the new client interface that facilitates short messages in a conversational style. SMTP is equally (if not more) capable of transporting these messages. Sure, SMTP is not designed for "instant" messaging. but todays use of SMTP where my local SMTP server talks directly to your SMTP server, makes email is just as instant.

Mailing-List 2.0: Discourse
You got a few people working on something and you seek for an efficient way to communicate (ideas, news, messages, etc.) online. This guide gives you an overview about what you could expect in the past and what you should ask for nowadays. Mails According to Wikipedia, the first mail was sent in 1971. The access to a network we call Internet today was quite limited in these early days. Users have been mostly universities, and I guess, not everyone, but mostly the STEM disciplines Science, Technology, Engineering, and Mathematics. So it comes at no surprise that mails are perceived as inconvenient and antiquated.

Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).
Email isn’t decentralized, and that’s fine
Email is open, but deliverability depends on a few big inbox providers. Why we traded some of email's decentralization to fight spam, and why that's fine.
