I'm interested in programming as a tool to give myself a clearer mental model of language, mathematics, computation, and thought, and I'm interested in writing and reading code that I find artistically aesthetic and elegant.
(Then again, I wouldn't call myself a 'hacker'. I think 'hacker' implies a large degree of making-cool-stuffmanship.)
Which isn't to say they aren't interested in technique. After all, carpenters still like to geek out over tools once in awhile . . .
[edit: well, wikipedia has a whole pile of different things listed under carpentry, so perhaps i remember wrong, or this was a local thing (my grandfather was an odd-job man in leeds, uk)]
[edit2: ah, perhaps the distinction was between carpenters and joiners, which is explained here - http://en.wikipedia.org/wiki/Joiner - and is a uk-only thing. certainly "joiner" is a word i remember, but that you don't hear any more...]
