There is if you're interested in the future development of the django framework. I am, and I found it interesting. Alex is one of the core leads of the django project and does a lot of good work with django and python.

There's obviously isn't high interest for most people here so they're not upvoting or commenting. If you're not interested skip over the slides.

I found it useful. It's like a guided tour of the Django models layer. This implementation is not useful to me personally, but I wish I had the breakdown (i.e. the onion description) when I started hacking on the internals. I'm still very into relational databases, and I do a lot performance tuning in that space, so I'm interested in how Django translates to vendor-specific code. Although that was not the ultimate purpose here, it was a necessary discussion, and I got something from it.
