i'm also interested, either in the end product or online, but i'm in GMT+6.
if the goal is to document the new user-visible goodies of ASDF, then even an hour on this specific topic seems to be a lot (time is scarce, we're all dying! :) but if it's about documenting the internals for people who intend to hack on ASDF, or documenting some of the nice solutions that are interesting even beyond ASDF, then that's a different story due to a different, more involved audience.
having a condensed textual blog post with links into the long video may be the best of both worlds.
