I used to read this comic about a decade ago, and stopped for no particular reason I can remember. Characters seem to have changed, and there are new ones in ongoing story arcs I’m not familiar with, but I don’t remember it being so feminist!

Wow, I *REALLY* like this webcomic! Thanks for linking it … I think I’ve read it once or twice before — like, the one showing patriarchy as the Matrix, that one’s really good, and I think it appeared in that strip — but I don’t know that I’d have gone back to it on my own.
So awesome. I like this one a lot …
