I like the blog title:  “If your only tool is a hammer…” I have said that so many times.  Developers learn one trick and want to apply it to every situation.  Sometimes Tool-A is better than Tool-B.  I suppose that is what separates an Architect from a developer.  Loren does a great job explaining the differences.
