Todd Cochrane who wrote the book on podcasting, Podcasting: Do It Yourself Guide, wrote a harsh post about Movable Type 4 not living up to its announced podcasting support claims. The article begins:
From today forward I will no longer recommend Movable Type as a viable new media blogging / podcasting platform. I will recommend WordPress to any and all that ask my advice.
Todd elaborates in the comments on the experience in WordPress that has contributed to his conversion:
Wordpress does have native support when you are publishing a post you will see add media at the bottom of the page.
If you add your media there and hit publish the media will be included as a enclosure in your RSS feed.
While you will not have all the fancy itunes tags you can manually edit your rss template and add that data to be included.
To make it easy the podpress plugin makes it easy for you to add the itunes data to the feed.
Another thing to consider is that at least you can publish a podcast with WordPress today. You cannot say the same with MovableType Version 4 it is simply not possible to publish a podcast with the current version of the blogging software.
