I can definitely see the long term benefit of a POB exchange listing or two... down the road.
But I'd submit that we're way too early in the game to consider such a thing at this point. The community needs to get fully established and perhaps have 12-18 months under its belt, and a fully functional front end of its own creation to help establish its own unique identity... not just as a "subset of Hive."
This "experiment" is definitely unfolding in an interesting way, and I can see the potential for down the road, but right now I think the community is best served by working towards creating and fully establishing its "identity."
That said, merely establishing an account designed to accumulate funds towards the payments associated with exchange listings might not be a bad idea.
