You're hitting the nail on the head.  Most people worry about the *tool*
being used, and neglect the information.

Most networks need at least two diagrams:
  - a logical map showing network boundaries/collision domains/etc.
    (This is where VLANs get documented)
  - a physical map showing *how* things are connected.
    (This is where equipment and their interconnects are documented)

Once you get that into your head, the best tool is the one that most
people can use.  I've been using PowerPoint for a couple of years and
haven't run into anyone that says, "I can't read that."
