I think these maybe missing: - My friends don't use this app, so there is the chicken & egg problem that exists with all social networking services (can I see public drawings?) - Assuming chicken & egg problem did not exist or you have solved it, how often the friends I am in touch with would draw a message in a particular place and send it to me and how often do I remember to check their message when I pass by that place? Wouldn't it attract more people if it would have been public so I could see any drawings, information about the building or poster images by anyone? Pivoting towards a pure anonymous entertainment/game maybe necessary? Overall it is a cool idea but would people use it without a big pivot? I doubt so or if they do I'm missing something here
