He will also be remembered for his blackboard presentations as "Ask Dr. Mike."
Born on April 10, 1957, he died at the age of 49 on September 25, 2006, after years of poor health -- actually having lived longer than he had expected.
A memorial thread is posted at Electrolite, along with several other threads collecting miscellania he'd posted there over the years. His Wikipedia biography has also been getting frequent updates and expansions.
A memorial service is scheduled for Friday, October 27, 2006, at the First Universalist Church in Minneapolis MN.
