I have finished moving plainsimplemanagement.com to Posterous.com.  I had completed most of the work previously.  Moving the podcasts from Wordpress to Posterous was automatic.  The heavy lifting was moving the podcast mp3's  and including them in their respective posts rather than linking to them from within a post.  I think this move turned out well.

I finished the task by pointing my A record to my Posterous site and updated the Posterous setting to recognize my domain name.  Voila!.

One advantage is that Posterous provides the mechanism to play the podcast using an embedded player.

Another advantage is that Posterous provides and RSS feed that can be linked to from iTunes or can be linked from Feedburner.  I currently use feedburner for statistics so my Podcast link references Feedburner rather than aa direct link to the Posterous site.

And another advantage is the Posterous provides an itpc link for use in iTunes as well. itpc://plainsimplemanagement.com/rss for a more straightforward link to itunes.

An overwhelming advantage of Posterous is that I now no longer have to pay for site hosting and maintain my own WordPress to publish the podcast.  This is a huge timesaver.

If you are thinking of starting a blog or a podcast, I suggest you seriously consider Posterous.  http://posterous.com
