Ah, I hadn't clicked any of the links. I thought you had just linked back to their site.
By the way, I like your site. It makes it easy to cut through the cruft that always appears in reddit threads. Do you just grab all responses by the poster and the parent comment?
If they have a full content RSS feed, then this use should be okay. But I hope it survives their scrutiny since this is vastly more readable then the native view.
It's an interesting debate, surely the content is owned by the writers?
