I've honestly never used AoN, though I have been aware of it for some time, but I have no feelings about this.
That being said, I do have one major reaction. I LOVE that Paizo is more than willing to work with members of the community and bring them into the "official" fold. It's amazing to see that they care as much about the fans as we do about them and are willing to reward hard work with praise and inclusion instead of with C&D and DMCA notices.
I love you all. Thanks for keeping the "open" in OGL
ALso, selfishly this gives me hope of getting one of my adventure paths to get an "official" publication
