An interesting and wide ranging podcast Doug.
I liked the concept of seams rather than seamless technology. Likewise I’ve found a bit of friction useful. Slows things down and gives you time to think.
The decentralised session sounds like an interesting way to run a session, it is, it might be too easy for experienced confident speakers to take over such a session, so perhaps needs a fairly egoless leader. Sounds so like yours went very well.
I think you asked for microcast suggestions? I’d be interested on your take on the IndieWeb as compared to federation.
