In late 2004, a means of categorizing Daily Kos diaries was devised by user anonymous coward 8 (Ancow8 on dKosopedia). This was at about the same time as the introduction of tags, which did the same thing, so ac8's scheme didn't catch on; however, much of the dKosopedia's Categories page is devoted to it. I'd like to clean up that dKosopedia page to more accurately represent dKosopedia's real Categories, but don't know if anyone is still using ac8's old scheme.
If you know anything about this, please comment below. If after a few days no one has screamed bloody murder we'll fix things up. Thanks.
