@aral this isn't a question coming from a position that supports ruthless capitalist endeavors (and that this needs clarifying highlights how disengaged from the problems at hand this polemic is), but how could a plan of action whose entire premise undermines the accumulation of profit be considered a business model?
@aral people use ibuprofen and they use heroin. the motivations for each respective consumers is the difference between satisfying a need and an instantly gratifying desire. consumer technology by a wide margin falls into the latter category, it'd be absurd to claim the innovations funded by VCs get returns because people truly _need_ another iphone app. facebook isn't heroin, but i don't think you can justify it as being non-conspicuous consumption
