Shyness or marketing strategy?

Recently I did a Q&A with GoodReads, for its newsletter. I enjoyed this one because it included a few questions very different from those I’m usually asked. Like this:

Q: Despite having multiple websites and a weekly column all jam-packed with your writing and ideas, a publicity headshot is nowhere to be found. Your readers also have to dig pretty deep to find any kind of biographical information. You don’t include anything like the “I grew up here and had these formative experiences” bio that is so common on writer sites. Are you shy or is this all part of a larger scheme of marketing yourself as a writer?

Here’s the whole Q&A.

(** As mentioned earlier, I’ll be answering questions (or criticisms, or whatever) from anybody who joins this GoodReads discussion group and chimes in. That’s August 11-24, but you can join and post questions or make comments anytime.)
