Honestly, it's not been that interesting to me in general. It's only interesting to me for the same reason it might be interesting to the sorts of people I enumerated --- because of the ways it can be useful to me. I don't really care about how it works, in depth; I just want it to keep my stuff private. The only difference is that I have just enough technical expertise, as a programmer, that I can see its applicability without having it explained in a sympathetic manner.
