I knew Bob/Kevin mostly through years of wonderfully engaging conversations about Doctor Who (as well as other science-fiction properties). I was always stuck by his calm and reasonable voice in those discussions, even in the face of fan hyperbole and outrage. He was the sort of poster that I would always stopped and read his thoughts, even when scrolling through a plethora of posts, because reading his opinions were always kind and insightful. I will greatly miss his posts in those threads. :(
