It fails miserably on my chalkboard photo test (it doesn't claim to support chalkboard, but it seems like it should - it probably doesn't take much to determine the background is all dark and run the appropriate scripts)<p>Your 4 step instructions have doodle@, but the actual mailto: is for wb@. It's a minor thing, but you should be consistent.<p>Cool idea. I think you could run pretty far with a posterous style lazy signup and more options (like the dropbox idea, some storage, etc.) Maybe support group emails, so dev@ when sent from my email address returns a response to a certain 5 people.
