A decent article on pricing, but I wish the article was contextualized in a larger discussion of revenue models that included applications that provide free services - its too much a part of thew new wave of web apps to ignore.
I'm just about to launch my online application - basically online storage using S3 with some pretty front end functionality specifically for the aerospace industry...I'm basing my monthly price plan on the amount of files uploaded (with a markup and covering an estimated maximum usage) but I'm also thinking maybe I should price it like most products and price per user with an enterprise "unlimited" package..anyone had any similar experiences where your costs were based in part from Amazon S3?
I think you should charge for the additional value of your app first. And add a small but fair cost to your expenses on managing user's data in Amazon S3. But in this case you should base your price plans' on features and functions first.
