Let me restate I am not going to question the obvious advantage a CMS can have for those selling web site construction.

A CMS is still a business communication strategy first. And many companies don't want to think about strategy, and the barely want to think about the web site. Writing is thinking, folks. Having lots of contributors producing all kinds of content means thinking about communication strategy.

It doesn't have to be a long involved discussion. Most business people will see all kinds of opportunities to solve genuine problems. And it is not like business people aren't having information overload problems. But CMS discussions often put the cart before the horse, then throw away the horse.

I would be the first one flying the CMS banner if the topic even once swerved from throwing up or maintaining web sites to include specific customer application. Beware the technologist who has found the one true hammer. Every situation turns into a nail in need of pounding.
