I wear two hats, professionally. One of them is a propellor beanie, and is my Science Fiction Hat (if you win a Hugo award, you get to wear double propellors on your beanie). The other hat is my Game Design Hat (which probably looks like this). I wore my Science Fiction Hat when I wrote the story "Periapsis" for the Hieroglyph anthology. But when I was interviewed by Joey Eschrich, one of the people who created that ambitious collection, I wound up wearing my Game Design Hat for most of our talk.
Put on whatever headgear you find most comfortable and read it here.
