Eric Meyer — co-organizer of An Event Apart — has written a very thoughtful post regarding web conference diversity:
Look at the authors of the best-selling books in the field. Look
at the folks behind the most widely followed web sites. Look at
the names that come up whenever someone asks who are the most
respected and influential people in web design and development.
How many are female?
A few. Not many. (And most of them spoke in Vancouver.) So is the
gender imbalance in the eye of the organizers, or is it in the
very fabric of the industry?
