"Im playing with it now and I think it's an improvement over the previous version. I was just talking to a friend yesterday about how the previous version had some bugs. Im curious though why they don't make this a platform for user contributed conversations though. This new version should allow you to comment on the comic you are reading and then to see comments from other readers. Add a filter to just see comments from your friends, perhaps. To me that would be the reason to switch over from paper to digital. "
I just found out that you can actually share the comic in a ton of places (facebook, aim, etc.), but for someone else to read more than the three page preview, they have to be subscribed. So I guess this is a step towards what you're talking about, which is an inarguably cool idea.
