This article was a good read, although I have no clients, no one to answer to but myself. My T1i was producing very pleasing JPEGs, so what the article is discussing isn't exactly new. It's written from a business point of view, but the point can still apply to hobbyists. Why spend hours in front of a computer if you're not getting paid*?
I myself always use RAW + JPEG, usually posting SOOC or printing the JPEG version.
* - assuming you've got other things going on.
