I don't think that's his point at all. He's saying that they are playing directly into Django's strengths and therefore Django should work very well for them.

Thanks for clearing that out. Most people who discuss Django and other frameworks seem to hammer out the point about its CMS heritage a lot: as a way of contrasting it from Rails' web app heritage for instance, with some strange insinuations inferred. However, a quick glance at djangosites.org suggests that Django has been used for a wide array of projects from ecommerce to photo sharing and dating sites etc.,(not forgetting a newly discovered redditplus.com). And these are just a small sample reflecting the rapid evolution of the tool beyond its CMS heritage.
