Yeah, I'm all over this. Everything about Glitch is so completely amazing that if any of the people involved are going on to have creative control over other projects, I want to know about it.
One more thought on an opt-in email list: you might want to set it up where we also have the choice to opt-in to your list of Awesome Beta Testers (for sale).
The beta test community here has been really impressive. If people were to knowingly opt-in, you could sell the email list to other companies looking for kick ass beta testers who will get their new game off to a good start. As long as you did it on an opt-in basis, I don't see any ethical issues with it, and I expect many of us would welcome A) the chance to beta test other games; and B) the chance to keep a big chunk of the community intact--as well as a chance to get as much revenue back to Tiny Speck as possible. I hope you'll consider it.
Yes, please. And does anyone know if there is a simple way (RSS preferably) to follow TinySpeck for the future? I want in on the Alpha of whatever they do next.
