If I may put forth a slice of my personal philosophy, it's that silly host names have ruled naming conventions long enough. I much prefer boring but logical descriptors that help my network self-document: whether simple codes useful in small environments (like "file01") or more complex schemes suitable for large-scale computing (e.g., "masip150ntvirt" or "cin-me-exch-01"). With the right scheme, 15 characters can tell you a lot about the location, ownership, configuration, and purpose of a particular computer. The cutesy naming conventions do nothing to help admins do their jobs or - in my opinion - actively get in the way.
