I guess it all depends on how you define "edgy." I've always considered "edgy" to mean "experimental," as in pushing the boundaries of the genre and the medium, trying to break just the right rules in just the right way. Excessive graphic sex, violence, and language is one of the easiest ways to do that, of course, and so has become synonymous with being "edgy" – but there are a lot of other ways to do it. I've seen more than a few "edgy" experiments that go in the opposite direction, becoming overly artsy, absurdist, non-sequential, etc.

I've read a few AInk anthologies, and although there a few stories here and there that I'd classify as "edgy" (by my definition, at least), the anthologies overall seem to be more or less mainstream.

Recompose, however, does seem very edgy – but then I get the impression it's supposed to be an experimental literature magazine.
