This is cool! I would make the screen shot bigger and lose the safari / os chrome so you can show more of it off. I keep reading that "Sign up" is a bad phrase

This is cool! I would make the screen shot bigger and lose the safari / os chrome so you can show more of it off. I keep reading that "Sign up" is a bad phrase lately, maybe instead that button should say, "Start collaborating" or something? Going for a niche like bands is a great idea, are you connected to any band scene yet?
