It looks like honeypenny is doing 21. Given that this coin is clearly superior to honeypenny on every other basis (first mover advantage, no block rewards going to the developer as free money, far better name, etc.) we should really just do 21 and remove a differentiator has the potential to hurt us. If the emissions curve matters, then honeypenny could outcompete this coin on that basis, and if it doesn't matter there is  no harm in having the same curve.

With the same emissions curve we almost certainly outcompete honeypenny. They have one or two interesting features but we can easily adopt those if they turn out to be useful, since it is open source.
