If there's a discrete moment of birth for a new podcast, it comes when you get the "Podcast Approved" notification from the Apple iTunes Store.
For Soonish, that happened today. I'm popping some corks here at Soonish headquarters!
The first full episode of Soonish will arrive on or before January 13. Once you subscribe, that episode and all subsequent episodes will show up in your podcast feed automatically.
Bye now—I'm off to celebrate.
