Popcorn is going to be published in bursts, with long periods of inactivity between the bursts. I certainly would not ask people to check in on a regular basis to see if anything new is present on a journal whose updates are so irregular, so I've set up a subscription option on Feedburner.
Just go to this page. The link will open in a new window, but be sure to leave this window open, because when you're done, the new window will close. When you're done, you can just return to my microblog or my Typepad profile using those last two links that you just saw.
