Why is it that the most common questions people have about providing open APIs are often about monetization? While there are many possible answers, two reasons that stand out are: a) the API is a distribution channel, and when you think new distribution channel there is an expectation around revenue opportunities; and b) if you are the person in your company trying to define the business case for an API to the executive team, there is a big hurdle to overcome, because business executives tend to see an API as a cost center and want to know how to measure the pay-off.
