Spammy popups? Definitely not to my knowledge. If anyone ever sees anything like this, please do take a screen-grab and email it to me - bill@justin.tv
I don't like the idea of a web cast for something like this, but if I were going to do one, I would use something like Hulu which is all the rage right now anyway. It is marketing, and Hulu has been getting a lot more air time than Justin.tv
A coup for justin.tv though.
