You have far more exercise equipment experience than I do, L. :)

Like you, I usually feel like my odd moments could be spent reading, but the combined experience of starting to walk on the treadmill and commuting up to Baltimore this past semester made me realize there *are* these periods of half-activity that podcasts would fill nicely. (I've never really understood before exactly when folks listened to them, to be honest.) Now that I think about it, they might be good for housecleaning, too... M.
