Must watch videos from DjangoCon

I was recently going through some of the videos from DjangoCon. Two must watch videos are Cal Henderson's talk titled "Why I Hate Django" and Mark Ramm's talk "A Turbogears guy on what Django should learn from Zope". Both Cal and Mark bring in interesting outside perspectives that I hadn't really considered before. Both talks run around an hour each and are well worth watching if you have the time.
