I think the idea feels more inclusive, and also sounds like an opportunity to take more detailed notes during the meeting (I would suggest that the facilitator and note taker are different jobs) - more/more detailed use of the chat area might serve to document conversations very nicely, since I think that can be copied into a doc right away at the end of the meeting, without waiting for the meeting recording to be posted, for use and reference by the other team. It also seems like it would be important to make sure there is plenty of cross-attendance, so that we maintain a sense of who each other are.
I think it’s worth a try, especially if it results in a lot more participation. For ease and consistency, I would suggest that the meetings be scheduled (exactly) 12 hours apart. I am willing to give it a try and also happy to attend both meetings (I learn an awful lot from listening and having the chance to ask questions).
Even though some people are willing to come at inconvenient times (i.e. the middle of the night), I think those may not be the times when they are at their best and can make the best contributions. @Permakai I have found that the global meetings tend to be efficient and jam-packed with important conversations, so I would not want to attend partially if I make the effort to get there (and once I’m up at 3, an hour long meeting is just as easy as a half hour).
