So either I'm getting too deep and forgetting the audience, or the whole of the presentation is starting to make sense. Still need the section discussing how to decide when to use them, and a review of how metaclasses fit into the goals of meta-programming. It's fairly clear IMO, however, so yay. It's a much longer presentation in terms of slide count, but the slides are much cleaner and clearer. The flow is still a little off, work on that tomorrow after work I suppose. Hands are shot now, need sleep.
