I've always been impressed by zzzeek's near-omnipresent participation. Years ago, I had a question about SQLAlchemy that he'd answered on the mailing list which amazed me given the relative rarity of developer interaction. Yet here we are almost a decade later and he's still answering questions directly, but on many more platforms. I'm actually not convinced he ever sleeps. I wish more people aspired to be like him, because you know there's no more authoritative answer when you run into a Stack Exchange post and he's offering up his assistance.
