Huh. I would've thought that position would require more official knowledge than I have. But yeah, if you want to know if something will work or be comfortable, those are things I can figure out ... at least for a subset of people often not including the middle of the bell curve.

I make a good sounding board, at least. It's gotten me hired in the past, albeit in a different context. If someone wanted to hire my insights for software or hardware development, I'd certainly consider that. I know how to do a lot more things than I can personally do, and I have a lot of ulterior information.
