I just discovered this (I’m slow) – you can subscribe to a podcast (which includes video)! …and I just set it up for Video Haiku. There’s no money involved, and no work, beyond pressing about two buttons:
Look at the bar on the righthand side of this page: underneath “previous posts” and “archives” there’s an orange button with a speaker icon in it.
Click there, and you’ll go to another site called “Feedburner” which hosts podcasts for free.
On the Feedburner site, just click on “add to iTunes” in the box to the right, or “My Yahoo” or something else, if it suits you better.
My future video posts will download to your computer’s iTunes (or whatever) automatically.
Which is awesome.
