I have met:

Miriel
Calliope
Strider
ShlupQuack
TheAbominatrix
Kawaii Ryukishi
Necronopticous
Cid
Cid's Wife
Buttheponcho
Pureghetto
Kalen

I must say meeting Miriel was the best. Also notable is that I met Nicky at the airport, and Strider at a Giants game. The rest were all at Amanda's wedding. I don't really 'do' meetups, but meeting these folks was pretty fun (except for Necro, he's weird).
