I like your abstractioneering section about slides (though not the title). Makes absolute sense: if your program is intended to communicate something to somebody, think of it in terms of something else you use for communication. I find I have to wait til I'd written a fair bit of a project before I can divide it up into modules correctly --- you need to understand a problem really well before know what the sections need to be. I guess in "giving a presentation" that you already understand the project and have finished it is implicit. But maybe your metaphor will help even in the process. I'll try it. :-)
