Hey, no need to start a flame and all. I personally use Visio as the corporate standard, and it does the job. I'd use a free equiv if it was pretty good and I was allowed to at work, but as it stands, I'm a Linux admin who uses Visio! :-) Wouldn't it be cool to see a network diagram document record its change history from when the company started to what it stands today? That'd be a nice feature. Hell, I'd play it as my screensaver! Expecially the security-through-obscurity parts...
