My impression on app.net, which seams to be a payed "twitter" if I understood correctly, is that it should provided an added value worth $50 in the eyes of customers. Publishers would very likely find this value is such service, but I doubt for readers. Twitter is already a time sink, so adding a cost to it doesn't make it attractive. Beside, how much different would be paying publishers from advertisers ? They will/should make sure they get their $50 back someway. Regarding the funding process, it shouldn't be considered as an idea validation process. Outcome depends on how well the idea or project was presented AND people's preconception on what has been presented.
