I'm Neil Broadley, a network specialist generally (firewalls, IPS, and so on), but I've been using Ubuntu since early 2006.
I'm generally command-line averse. It's a critical aspect of linux, but I believe that people learn best through experimentation and therefore believe that GUI tools are essential. To that end, I'm (slowly) learning Python in order to scratch a few GUI itches.
