I've been working this week with Myles Braithwaite's Django Tumblelog (and doing some heavy-duty surgery on it) and James Tauber's Django-Friends, when I suddenly realized something: if you replace the explicit User object in Friends with a generic object, you suddenly have an entire framework for expressing an interest in, not just what other people do, but in everything that happens within a given system.

You have a better social network engine than Pinax.

You could build friendships on top of this model. You could build a hell of a lot of things-- not all of them efficiently-- on the basic idea that "object A is interested in object B."
