I'll second DZ. He should at least be nominated every year, and should win at least one. Lots of helpful, educational posts over the years, and of the (very) few seminars I've attended, one he gave at the MSBA show a couple years ago about lunar phases sticks in my mind the most. Those on the list already, as well as the ones we haven't thought of yet are all very deserving also, and my hat goes off to all of them.
