This sounds like a great idea!
But I think it's going to take a lot of administrative work to put together. I'm friends with the guys that put together Black Torch (an absolutely beautiful anthology) and just hearing about all the work put into it is sort of mind numbing.
However, if you're really interested in doing this, I'll be more than happy to assist you in any way possible.
On the bright side if we curate the best of Tapastic, well most of the content is already made and we just need to get permission from the authors. But then again, I think curating is slightly difficult, like picking and choosing what gets in and what doesn't.
