A puzzler from Macupdate

Today MacUpdate launched a new thing called MacUpdate Promo, which does 24-hour steep discount sales on popular mac software. Um — how is this different from macZOT!, and if it’s not different why are they bothering? I suspect that most people who care about the sort of thing macZOT! does already know about it, so I doubt that the additional audience of MacUpdate will do them any good here (and who reads the MacUpdate charts regularly, anyway?). It’s not that I don’t think that they’ll make any money from it, but I do think that there are better things they could spend their effort on, given that something like this has been going on (rather successfully) for some time. This one’s a puzzler.
