good points to which i agree.

ASFAIK Jerome and many others in this MLs context are using and
supporting GPG. I certainly am. it's one thing i intend to talk about
friday morning actually in the decentralized networking session.

Also from what you describe below i am not sure i am up to date on
current keysigning "party" practises. Last time i attended one
people insisted on seeing an ID/passport for signing my key.
is this still the case?

This practise i consider kind of decentralized policing. For me it's
enough to associate a physical someone with an email and public key.
I don't care what kind of government numbers that person has.

And to be honest i most often use and advocate trust on first use (TOFU) --
and then, if it becomes more important, verify by other channels, including
personal meetups, cross-signatures. Staging MITM attacks on TOFU is
possible but hard to do undetected on a mass scale.

Advocating TOFU doesn't speak against furthering the Web-of-Trust. For
me, it's not an either-or. But people can start and should be encouraged
using GPG right now and should not be required to attend a crypto-party

So all in all looking forward to signing your and other keys soon :)
I don't know about timing and talks currently but i am happy
to discuss things more in depths on-site. Are you in Berlin
earlier than saturday?

greetings from a train to berlin,
looking forward to you all!
