Far too often on this site, people will talk about usage but not say where their experiences are from.
I live in Golden, Colorado (near Denver). I lived most of my life in Iowa, and a few years in Texas. All of my usage experience is from those locations, the people I met there, and media.
I'm a forensic software engineer at a private test lab. That means sometimes I write software, and sometimes I do forensic investigations on computer systems.
