John Battelle kicks out a fascinating idea to change the face of online advertising to better fit citizens's media. Then Jeff Jarvis kicks it up another notch. If you have any interest in citizens' media, the technology and economics of funding such, and novel business models (and if you don't, what the heck are you doing here?), then RTWT. Plenty here to drive any conventional ad manager or MSM owner batty. The discussion is happening in the comments to John's post.
