Yer basically playing out a concept to see if you can do it and then you can either break it down and turn it into a licensing kit idea for people and get the masses to start creating their own, and adding their own personal style to it.
If you don't sell it ya got about a month until someone learns from your idea and rips it off and now yer bleeding.
Still isn't sticky.
You could play it up more and do more truman like things to it, but then yer dancing into the realm of staged content, and the real effect could wear off, but as if people really think reality shows are all that real anyways, theres always a camera man there watchin people.
I dunno. Still biggest thing for me as a would be watcher, needs stickyness. I like the fact you can embed justin like a widget, and all the bits you have to rss it out etc is nice but overall stick is lacking.
Spend, Build, Learn, Craft, License, Sell thats yer best bet here. I seriously doubt these guys can go a year, and if they could i mean my god, gun to head please, eventually the audience will WANT you to turn the thing off. People like blogs for stories and threads and ideas that get manifested into an entry, in a real time stream, that after thought processing isnt there, so you may see it you may not, stickyness is relying solely on the person in play and whether or not somethings really interesting to see.
