I'm writing the actual prose text of my talk for this presentation, because I want to see how long it turns out to be (doubtless too long), and also to let the argument drive the presentation rather than the presentation materials driving the argument. I've done about two thirds of it today, and also begun converting some of the graphs into graphics I can use in the presentation. I may end up dropping a lot of content relating to the use of containment metrics in SC, because the Jaccard Distance calculation is more appropriate and relevant. That'll simplify things a bit.
