The french comic pirate scene has an interesting rule where they keep a ~6 month time lag on what they release. The scene is small enough that the rule generally works.
It's a really good trade-off. I would never have gotten into these comics without piracy but now if something catches my eye, I don't mind buying on release (and stripping the DRM for personal use).
Most of my downloading is closer to collecting/hoarding/cataloguing behaviour but if I fully read something I enjoy, I'll support the author in some way.
