Brent over at inessential.com (the guy who created NetNewsWire) has a nice post on XML-RPC. I agree with him 100%, no web services protocol is as easy to implement as XML-RPC. We plan on using it alot in our Help Desk Software with limited support for essential functions in the beginning and greater support over time which will enable customers to fully integrate their help desks with other systems.

Here's a hint for those of you following our progress, how's the idea of reading and responding to help desk requests in your weblog reader/editor strike you? ;-)
