Single Topic Series, Best Single Issue
OK, I didn't win. But I was a finalist twice -- once for a series on Internet Privacy that ran in PC World in 1998 (I was special issue editor), one for the September 2002 issue of Popular Science (I wrote one of the features for that one, which was nominated for best single issue).
Does that count?
The good news: I got to sit right behind Martha Stewart at the 1999 awards ceremony. You wouldn't know it to look at her on TV, but she has a caboose the size of Montana.
