@Linda Yeah, my vision which I described in our call was not to have strongly stable pods but more of flexible-ish working groups, plus mixed interaction seminar-style on an ongoing basis, and the option for at least mentors to be around part-time.
I'll be exploring this with Attila, who wrote that section. He brings a ton of experience with relevant events and will be doing a lot of the event design and he's excited to make this awesome, but we've only partly synced on models of how to best do that. My guess is we end up having more working-group style group layout rather than strongly stable pods, but I'll be examining his reasons for having put this into the draft plan here.
My main reason for wanting flexibility over the usual benefits of having more fixed pods is that this seminar, unlike most similar events, is much more focused on gaining lots of existing knowledge and helping people rapidly grow than producing novel outputs. This means having more intermixing and people switching so they can tutor new people on the things they've collected is unusually beneficial, as opposed to the usual thing where you want to get deeply synced with a few people so you can push the boundaries of knowledge and do a project together.
In general, we're planning on iterating the details like this a fair amount as we approach the date, and have been keen to get this out ASAP so we've got longer with funding confirmed to start collecting candidates.
