Unfortunately StackOverflow hasn't aged well over the past few years, mostly because of way, way, way overzealous killing of "duplicate" questions. (IMHO, if it's not literally a word-for-word retyping of a previously answered question, it's not a duplicate.) But whatever the theoretical merits of it, this no longer works now that every system is following the CADT release model. A question that was answered perfectly well 18 months ago requires a completely different answer today, but the re-asking of that question today gets squelched with visitors being pointed to now-obsolete answers.
