I've seen you ask that numerous times, Janus, so here's the official answer as I see it: midwinter one day said he loved the site and was excited to be part of it. He was pleased by my reassurance that I didn't plan to fold things up, because he hoped to be part of it for a long time to come. Then a few days later, he vanished without notice and seems to have never returned. He is online still and has a gamerscore well over 100,000 at this point, seemingly doing nothing but play Xbox 360 games. Any attempts to contact him are ignored. All I can figure is that he just loves playing Xbox 360 too much to care about anything else.
"Too often we enjoy the comfort of opinion without the discomfort of thought." - John F. Kennedy on reality
"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
