It was indeed a nice talk.

This was also covered; one of the crucial antispam mechanisms of Signal
is the use of phone numbers as identifiers, and even using the "desktop"
client requires to approve using the mobile client first.

I personally see more email spam than XMPP spam nowadays, but as a
server administrator it’s the opposite, having to watch for automated
registration patterns. A reporting and reputation system would go a long
way towards reducing the amount, and maybe a multi-tiered system would
work (I would hate to prevent people from creating and connecting to
account from Tor exit nodes, but at the same time we have a lot of bogus
registrations and spam and DDoS using it).

One of the points was that the dichotomy between applications and
accounts is only an issue in the federated world, as most "apps" are the
only way of accessing the silo, and even gmail which offers external
POP/IMAP/SMTP connectivity is still primarily used through the web

I think ideally clients should provide clear defaults like what
conversations does, and of course options, but hidden from the view of
normal users who don’t understand this kind of things. This is sad (as
it might lead to “megaservers” for popular clients), but that really
needs to be straightened out.

I could envision a "pick your username" dialog giving new users a
random server among a list of curated services.
