The idea of a launch-day stream is a good one, and I appreciate the limitations of having the core staff be US-based while the authors and readers are a bit more globally scattered. While it’s impossible to make the livestream accessible to everyone at every timezone, every job and sleep schedule, etc., you can make the Q&A portion of the stream more accessible by polling for questions in advance, here or on Twitter.
If the streams are successful enough to become regular (say… every other week, maybe?) I’m sure it will be appreciated by those of us who have limited time to browse the forum.
Lastly, congratulations on what appears to have been a quite successful first stream!
Edit: I forgot to link to my favorite timezone converter. I find that having a link for checking one’s timezone easily makes everything just a bit more accessible.
