Thanks for the support. I've already had 500 downloads today, and it's growing. Hopefully this means there's some interest, which will keep it happening. I wanted a good reason to keep up to date with LKML ;)
I would love to hear from people as I play with the format: what tree summaries would you like at the top of the podcast (current Linus/mm/next...) and what announcements would you like included?
I'm aware that non-native English speakers might have difficulties - this isn't designed to replace LWN or other news sources, merely to digest the LKML into a commute/travel/iPhone-at-bus-stop quick 3-5 minute catchup. And if there's interest for other non-English speakers, we can hopefully get someone to translate in the course of time.
P.S. The podcast URL will remain consistent, but I've already asked a couple of larger projects for help with mirroring/hosting of the mp3s.
