I'm in the middle. At work, I play it fairly conservative, applying well established solutions to well-known problems.
I have friends whom I advise and assist with their networks that absolutely fall into the first category.
MY network is is like the lab of a mad scientist, everything tinkered with right up to the edge of breaking. My home router collapses multiple times a year due to the wonky chaos I ask it to do. Home automaton sequences that are more complex than most rube goldberg machines. Metaphorical sharp edges and loose clutter everywhere, but an unholy abomination that works better than it has any right to - until I scrap it all to rebuild it from scratch next week.
