I'm trying to capture this for myself, mostly. I want to put together better information to pass along, and have a chance to decide which parts might actually need to be delivered via a website (articles for students, etc.). I expect I'd get a few minutes of something useful every few classes, and every now and then it'd be something I'd want to codify and make available without me having to stumble back into saying it again. You'd be amazed how little of what I say I remember later. My memory for detail is stunning in its absence.
