The well? very interesting. I heard about it while BBSing in the 80s. I was too young in the punch cards era, but I had a chance to see 8 inch floppy working in my school and used the 5.25 floppy a lot. Back to HN my behavior seems to be more compulsive than yours (unfortunately) and I am probably much more influenced by current rhythms. Thanks for your contribution which offers interesting food for thought.
