Another free article marketing site to consider is
http://www.leadmaverick.com. The free version allows unlimited content postings (including podcasts) plus an RSS feed specifically for the content posted.
On the
down side the free account includes ads, you can't change the logo and you can not include hyperlinks (features of the paid version). It does come with some reporting features on viewing patterns.
The nice thing is that all of the articles you post include an RSS specific to the what was posted. You can then use this RSS feed in ITunes (for Podcasts) or other sites for additional content syndication. All postings are automatically sent to Ping-O-Matic.
Not bad features for free...considering I created it
