People aren't used to seeing languages (, products) developed in a "visible but closed" beta. It is, initially, quite confusing.

It makes more sense to see it like game development, which I think it's blow's pov. He's not an open source developer, he's a game developer. And he's making a product he wants to be complete and correct before release.

I think there's quite a lot of good-will towards Blow, and I imagine he has some clout in the game dev. community. My sense is that when he releases his game written in this, and gives it its final syntax-and-semantics pass -- he will get buy-in from some places (esp. indies).
