I don't often (err, ever…) reply without reading further but this time I must, because: I've never heard this turn of phrase "useless use of cat" and it turned my brain upside-down for a moment, because: "interactive" is precisely how I learn and do and I suppose it was a nice reminder that sometimes really big (read: useless) things are actually kinda small (useful) and vice versa.
