Mark doesn’t buy the Podcasting hype.  He’s not knocking podcasting per se, he just doesn’t believe people should plan to make money as podcasters.  He equates it to streaming radio.  I like this comment he made:

Repurposing industry
  specific information from tradeshows, speeches, product presentations for employee or customer education or as sales
  support. No brainer. These are just extensions of existing content into a new low cost medium.

That’s where my interest primarily lies.  I hope NPR starts making their content avaliable via downloads.  MSNBC has.
