I once went to a Business Objects user group meeting, I think it may have been at the British Library. A BOXI evangelist was suggesting to the group that productivity would be increased by un-installing excel, and just using Business Objects. He suggested it'd lessen the danger of 'cottage industries' where mere users create critical stuff that just they know about, and then when they die or leave, other people have to pick up and try to understand. Most people could see his point, but ultimately, it's just too fucking useful. There would have been open revolt.
