i have mostly one complaint about nostr (the type codes) but otherwise idk. it seems fine as a screaming in to the void mechanism?

XMPP not too bad its okay. would take a bit of bullshit to make stuff for but eh.

deltachat is whatever. had nobody to chat with. might still play with webxdc.

email i would just change smtp to handle binary files properly. the biggest ass with deltachat is all the fucking overhead through encryption and base64 encoding vs. if we just transmitted binary like we should be doing. dunno what kind of herculean efforts it would take to get binary smtp in the wild.

anyway idk
