ikr?! i'd personally be more keen for a #logseq (at least the basic influeces from #workflowy) on nostr (data on device and/or secure sync). it's so good. 

email is not worth it imo.

it was never a secure communication tool. email is what it is. aliases as the way to go with that afaic, in addition to your "formal" email with your legal name attached etc. it's a form of online identity.

pgp is an awesome band-aid, but a band-aid nonetheless though proton is contributing to it's open source development and evolution, so that's pretty cool. 

but, if we get something like simplex on nostr, it would be way cooler with more security and privacy for communication, zaps etc. imo
