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

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.
