Compare and contrast.
A common trend still is that there are no generally accepted definitions of (web) services, and people spent way too much time criticising each others definitions.
Dan Connolly wrote, this in response to a question regarding the value of dereferenceable URIs;
my answer to “but what if I don’t want to publish representations or descriptions of the thing” is: then you’re not doing what you can to establish consensus around your terms.
My point being that perhaps if there were more Web services to which people could look for definitions, conferences like the one Werner’s attending (not to mention the Web Services Architecture WG and indeed most other Web services standardization groups) could be more productive.
Nothing facilitates concensus quite like running code.
Don’t chicken-and-the-egg problems suck?
