A co-worker of mine is a techno-geek. We laugh at each other, our hobbies are at either end of the spectrum. I like the old, traditional way of doing things. I use vintage mechanical rangefinder cameras, process my own black and white film, and make wet prints in a darkroom. I write with a small collection of fountain pens, and I have a handful of mechanical watches.

In short order, these developed into what the corresponding forums call:

Camera GAS (gear acquisition syndrome)
Pen Acquisiton Disorder and
I became a WIS (Watch Idiot Savant)
