Not much to tell other than I run a bunch of websites. The most recent, and pretty popular, is LOST Desmond.com. It's a site devoted entirely to the LOST character of Desmond and it's supported by Henry Ian Cusick who plays Desmond.
I also fell into writing fan-fic for Desmond and am just about done with my second of two. You can read them here if you want: Lost In Desmond's Eyes - Fan Fic by jbdean. With season 4 not starting until Jan. 2008, I have a feeling I'll be writing a couple more fics to tide me over until.
