Charles Cook: The very informal API specs that XML-RPC seems to attract are often wrong, or misunderstood so that the server implement something different. Businesses are using XML-RPC for serious purposes and this potential for confusion wastes time and money. [via Simon Fell]

Agreed. I still haven't found an answer to the question as to how one codes multiple categories in a metaweblog API. If you are going to pass structured data, I find the SOAP serializations are much simpler and easier to understand than XML RPC.
