Considering the recent publishing-related posts coming out of 37s, along with Jason's teasing announcement of a new product (and their history of building up hype leading up to a product launch), I put good money that their product will be a publishing app/service.
This. The idea is so good I was ready to "drop everything and do it" but I can smell from the post that 37s is about to release the service they're asking for and would blow me out of the water.
