I leave town for a couple of days and I miss my moment of fame on Slashdot. Ah well. My blog post doesn't exactly argue it's "business reasons rather than technical ones", although my post does dwell on the business reasons too. There are plenty of technical reasons to hate SOAP too. For my view on that, see my blog post about why SOAP sucks. Bottom line is SOAP is too complex, doesn't work well in practice, and strong typing is the wrong choice for loosely coupled distributed systems.
