She mainly mentions Ruby. Which, more so than other languages, actually does seem to be much more than just a language to the developers who use it. Knowing her husband loves Ruby to her also speaks to his programming philosophy, community involvement, etc.
My question is: how many geeks work only in one language or write to only one platform?
Some of us do a lot more than I think you can reasonably expect a non-industry spouse to follow with any technical depth.
It's like expecting a prolific musician's wife to identify all the instruments her spouse plays and have some understanding of why he chooses one over another for a given piece, just because you could reasonably expect a blues guitarist's wife to know that her husband plays predominantly blues guitar.
