This thread at Ask Metafilter is surprising. Yes, you’ll find the usual suspects of The Sandman and Y: The Last Man, but the recommendations are for a real woman (and quite often, from real women). It’s much better than any “How to get your (quite possibly fictional) girlfriend to read comics” list I’ve seen, even when it covers much of the same territory.
There’s a great mix of stuff in there and while I’m sure interest in responding will drop off pretty soon, I’ve been watching it with interest for a good portion of my evening.
