If I could be guaranteed that a gender-bending Canadian torch-twang-pop singer would be the only person ever to be associated with the all-lowercase conceit, I'd be inclined to cap and let cap. But people are weird, and they're not getting any less so. It won't be long before reporters start submitting man-on-the-street quotes from "john smith."
From a Columbia News Service article on "cuddle parties":
REiD (the mix of capital and small letters is by choice) Mihalko, 36, and Marcia Baczynski, 26, self-described healers and sex educators in Manhattan, originally conceived of cuddle parties as a way for their friends, deprived of human touch, to get a regular dose of nonsexual human contact.
UPDATE, Sept. 2: GQ tells us about "REiD (yes, that's how he writes it)." Apparently the G stands for "dumb-" and the Q stands for "-shit."
