I am mildly obsessed with functionality and efficiency. Hence the neon orange hair. It's fun, yes, but it has also allowed so many friends, IRL and materializing from the Blogosphere, to find me instantly. I am just tickled at having writers like Shark Fu, Vicki Forman, and Kristina Chew find me, rather than my usual MO of slinking up and mumbling about how much I admire their work. Fun!
However it also makes it much more difficult to discreetly slink out of panels, etc.
