The TopCoder reference is a really odd one. Code written in programming contests is generally not written to be maintainable. Rather, the focus is on submitting it fast and having it pass all tests. TopCoder contests, with their challenge phase (where participants review competitors' code and benefit from finding bugs in there), seems to particularly encourage writing obfuscated (and therefore unmaintainable) code.
