I think Exchange has always been a valuable product in every version I've used, but I find it rather mind-boggling to ask the same users who spend money on the product (and all the related products like Windows Server, Outlook, Forefront for Exchange, and premium CALs) to also do the tedious legwork for Microsoft.
Maybe a slightly larger carrot than "when you pay us for the next version you'll like it more" would motivate us? I'm perfectly willing to accept a 50% discount on the next version. Or maybe some free vouchers for the techs collecting all the information on their continuing education? A voucher for any one of the MCITP EMA exams would inspire me.
But I'm busy enough with my own projects to bother helping you guys make more money without any compensation.
*crossing my fingers on those vouchers, though*
