(Worse, they may not even care that much, as from their point of view, they're putting on their own convention that just happens to have the name "Worldcon" attached to it. We hope the top management feels otherwise, but so many unwise decisions are made by people at a much lower level, and they tend to be resentful when the Chair makes too many detail level decisions for them.)
This is one of the reasons, for instance, behind certain Worldcons using microscopic type on the names on their membership badges -- the person making the decision was unaware that doing this really annoys people. Back the last time this happened, WSFS charged the "Nitpicking & Flyspecking Committee" (which tries to deal with certain technical issues surrounding the WSFS rules) with nagging seated Worldcons periodically to remind them that WSFS wants name badges to be printed in large, bold, easily readable type.
Last year, the Business Meeting gave the NPFSC another such nag -- which we promptly forgot about until we were putting together the Resolutions and Rulings of Continuing Effect. We've taken steps to reduce the chance of this happening next year.
I'm on yet another committee that is considering proposing adding another nag order to the NPFSC. I suggested that the proposal be titled the "Discouraging Wheel Reinvention Act of 2007."
