Heh I'm aware that devs aren't free, being one myself, but a few devs can create a content distribution system that rivals the reach of a many, many million dollar printing and delivery infrastructure. Reasonably priced servers can serve up a shocking amount of content when caching is used properly. So, much closer to 0, and the marginal cost of a reader is effectively 0.
Okay - as a dev you should know that hosting is not cheap. Does it cost Twitter nothing to 'delivery' its content?
As someone who can peak behind the curtain, I assure you that its not free. Maybe cheaper than physical home-delivery of thew newspaper, but its not cheap.
It should be surprisingly cheap in relative terms, not necessarily in absolute terms. I would imagine that the NYT is much more cacheable than Twitter, given the nature of the site.
