I began programming as an Electrical Engineer in the microelectronics industry more than 30 years ago.
I have always used very specialised automatic test equipment, which gives me an unusual perspective on how to solve software problems (usually by myself without recourse to libraries and frameworks). This is definitely not mainstream, but I don't create commercial software: my user-base is my fellow employees.
My contributions to SO probably seem other-worldly, but the programming environments I've used have never been Windows-based and only vaguely Unix-like.
HOWEVER — In late February 2010, I was admitted to hospital with a suspected stroke. Tests showed it wasn't a stroke, it is Multiple Sclerosis. Thus begins an inevitable slide into disability.
While I'm now back at work, hopefully for a few more years, I think the effort of engaging in SO (after a lull of over 12 months) might be too much for me. Besides, I can't type as fast as I used to.
Maybe hanging around SO would be some kind of therapy, and expose me to new ideas. I may even ask the occasional question, but after the sabbatical I had, I notice far more low-quality questions left by drive-by posters who typically leave poorly-worded questions and don't stay around to answer comments asking for clarification.
