Eerily enough I actually met Satyriconhome at a game (long before I was on Demonland so I can't really compare the two experiences).
Since then I have had the occasional conversation with fellow Demon supporters when I have ended up at games without my usual cadre. (Saturday @ Etihad being one case where I chatted with 3 or 4 random other Dee supporters).
I've often wondered if any of them are on Demonland but generally refrain from asking for various reasons.
None of the people I have met at games however, have had the uniqueness of Chris from Camberwell.
