so far I am not seeing anything much different than various open mics I go to! I think that is a better model to compare to than a paid gig with pros. yeah, if I paid $25 you better not be farting around with your notes (or using backing tracks but that's another thread!) but considering the setup and the newness you are seeing this thing evolve into what it will become. I'd bet money that, if it survives and takes off, you'll have more pros doing this a year from now.
