I’m sure all the major directoies would be a great idea, I just used those two as suggestions for my marketing guide.

That would be kind of like being indexed in Google and not MSN, you’d still get good traffic, but not all you’d hoped for.

does the video tutorial recommend subscribing to the major podcasting directories too? Or just to itunes and mp3.com?

That would mean extra-visibility for your podcast series, I think.

Thanks for recommending this resource, btw.
