The "public" is not at the Creation Museum. It is, however, audience to YouTube. That is where the larger younger audience for Nye's teachings can be most effective, not giving aid and comfort to Ham in Ham's own home.
As Percy has already pointed out each side will claim victory. The videos will be put up on YouTube for all to judge.
Then, and you all know this is going to happen, Ham and company will put up edited videos showing Nye/science at his worse and Ham/creation as the shining star.
If you are correct and he is trying to teach, Nye needs to improve his delivery and the class of his videos, which he very well knows how to do, and teach through that medium. That is the biggest and most important audience Nye can get. Going to Kentucky, IMHO, is a trap and nothing good can come from it.
