The June issue of Curve Magazine included a really large feature story called "Dykes in Comicland" by Lori Selke with illustration by Colleen Coover. There were also several sidebars on web comics, superhero comics, and manga, with contributions by Jocelyn Voo and Diane Anderson-Minshall. Unfortunately, the article is not available online, and although it's possible to order the back issue it appears in, there's an order minimum of two issues.
The artists discussed include Elizabeth Watasin, Roberta Gregory, Dianne DiMassa, Alison Bechdel, Colleen Coover, Paige Braddock, Gina Kamentsky and many others. It really is a generous overview, and comes at the question of women in comics from an angle outside of the usual industry-centric focus.
I've also noticed that After Ellen has been giving more feature space to comics recently. Their most recent feature is An Introduction to Yuri and Manga.
