This morning I listened to the first Gillmor Daily podcast with Steve Gillmor and Dave Winer. The one comment that stuck out in my mind was Dave's about ads in RSS.

Dave said something like, "I thought RSS was the ad?"

Dave's thinking is if I am a business or a topical expert, any blog post I make could be considered an ad. By giving out a little bit of intelectual property you are attempting to attract interest and business.
