The guy didn't ask if his job justifies Drupal, he asked if its the
right tool for his job. Anybody who says that their preferred tool is
the solution for any and all problems is a fanboy, not a professional.

I gave an informed opinion that it's not. I base that opinion on
spending a lot of my career selling technical and advisory services into
markets similar to the one he's in. It happens that I've ALSO spent a
lot of time building web sites for both my own businesses and for
clients, and along the way built a hosting company - and understand all
too well what's involved in operating and maintaining content management
infrastructure.

I'll stick with my opinion that Drupal is overkill for a consulting
business that's using their web site as essentially an electronic
brochure.
