As much as I love the idea of Delta Chat, and even tried to set up my own relay server (which is too complicated and failed), hosting a poll in an echo chamber is going to skew the results somewhat.

I'm firmly in the #XMPP camp, and have been self-hosting a @snikket_im server since 2020, although I'm still interested in running a Chatmail relay for those who are not willing to replace WhatsApp with anything other than Signal.

I'm certain that if this poll was held by the XMPP community, the balance would swing in a different direction. Same for #Matrix.
