Technical hacking communities (like the Chaos Computer Club) seem to be full of people who enjoy aspects of computing in a pure sense. For example, they may hack long-obsolete game consoles, on both hardware and software levels; or sit around on a busy street cracking wireless connections. When asked how useful it is, they shrug like an ideal pure mathematician: it's not about being useful. They delete the creditcard numbers they find, like fishermen throwing back the fish they catch.
(Though many of them hate their day jobs, and even the economic system itself, even if they're well-paid. These certainly aren't going to gush about what they experience during the day.)
I don't know how other people use Stack Overflow, but so far I've only visited when I want a quick answer for technotrivia which isn't particularly mind-expanding. (Like, how to get Gnu Screen to stop doing this, or what Unix incantation does that.) If others do the same, then I can see why there would be less technical fascination and curiosity on display there.
