Well, it turns out there's a very powerful feature baked into Django which can handle the task for us.

Django includes an internal "dispatcher" which allows objects to listen for signals from other objects.

In our case, our tumblelog app is going to "listen" to our Entry and Link models. Every time a new Entry or Link is saved, those models will send out a signal. When the tumblelog app gets the signal it will automatically update itself.
