Seeing the answers already posted (with which I agree), this is has to 
be a good question!

What I would like to add is that I wonder if it makes such a difference 
since SOAP is only a thin layer on top of a web architecture that's 
already there.

You can easily implement API like web services over HTTP+HTML (by 
defining a mapping between URIs and classes and methods and between post 
or get parameters and methods parameters and a mapping between your 
result structure and your HTML document).

Thanks to XML, you can also consider your SOAP requests and responses as 
XML documents and use any XML tool to generate a request when you 
receive a message.

The amazing thing with a XML document is, like with a book, that the 
meaning of the document is what the reader wants it to be and, as long 
as your response may be considered as valid by the SOAP client, you are 
free to attach the meaning you want to a SOAP request and process it 
with the tools and mind (document or data) you prefer.
