Best Buy is joining in on the Denver Post’s podcast conversation for $30,000.  Titleist is starting their own global conversation for the same price.  

"Why pay someone else to hitch a ride in a conversation, when you can host it yourself?  Much more cost-effective, and appreciated by customers.  People don’t like intrusive marketing as much as they like finding commercial information they’re looking for."

Titleist decided to use RSS-as-advertising instead of advertising-in-RSS (this is a great example of the Web 2.0 thesis).  Dave Winer points out that there is a void in weblogs and RSS in the field of golf.
