Sorry for the short posts today. Still recovering from the server crash.
There is a thread at Search Engine Watch forums named Do Men and Women Search Differently? which discusses that topic. In addition, a poll is set up where you can vote:
Question: Does gender matter in search? Answers: (1) Yes - Viva La Difference! (2) No - any differences are due to practice, etc (3) Yes, but not enough to matter
