A discussion led me to be reminded of Dan Bernstein's proposal to create a better replacement for email, 18 years ago: https://cr.yp.to/im2000.html
@mala it sounds a little like a proposal for people who thought the problem with email was that there was too much reader privacy
@npd oh good critique!
@mala I keep coming back to that proposal every once in a while. I've been thinking about how IPFS is almost-but-not-quite perfect for implementing IM2000. What was the context of the discussion that reminded you of it?
