I wouldn't quibble with the adjective archaic. But let's examine it in a little more detail. QuickSat is written by Mike McCants, whose visual catalog was cited for its excellence in Sky&Telescope Magazine as long ago as 1971. That's archaic. As far as I know, it is still the best available catalog, despite my efforts and many others. Now how do you assemble a fine visual catalog? You observe a lot of satellites. A LOT. That is where QuickSat shines. I would guess, from my own experience and that of many others reported to me, that people who start using QS, begin to see about 3 times as many satellites as before. Many of these non-archaic interfaces fit beautifully into the "baby-sitting" model of computing; buy a bunch of equipment and hire a bunch of people to baby-sit it all day (I have a bunch of models of computing which I might mention from time-to-time). QS has a specific purpose and it fulfills that purpose excellently. Cheers. Walter Nissen dk058@cleveland.freenet.edu
