If feedback was listened to in the forum by administration and there was a chance that it was heard, listened to and potentially used to build upon the new forum software idea, I'd be much more motivated, though I am sure we can all agree that would be ignorant to assume.
Then, set up the demo forum, decentralized and with access to the general public, via the .com/.org domain. And present it to the public.
I believe that, if Bitcointalk does not migrate to this service, you will be able to sell it with some ease and make good money.
