There are discussions about APIs for web development and how to present your services to developers. Marc has some good points but misses something crucial, something the web should have taught him long ago. The best developers tools are the same tools everyday users use for... well usage.
The web is an excellent development platform because users and developers share the same data, structured the same way. It's not good because of the structural quality, html certainly isn't well structured, but because it attracts many developers, many people who document the medium, many people who find bugs and many end users who will go elsewhere if your service sucks.
