How not to implement RSS

Rok Hastrik, author of 'Unleash the Marketing Power & Publishing Power of RSS', has written up a good case study on how not to implement RSS.

The subject of the piece is AdAge.com, a marketing publication. Bottom line? If you try to subscribe to their RSS feed you'll get this
- a registration invitation with zero value proposition. Given
this is a marketing industry publication for markters, I suggest
they read Rok's advice and republish the article in their next edition...oh, and change their RSS plan.
