Not sure about the intentions of the reddit founders, to be honest, but at the beginning there were no subsections and the like. When they did show up they were implemented as sub-domains, for example http://programming.reddit.com http://programming.reddit.com . I can't exactly remember how much that lasted, but it was for more than a couple of months (I'd say for at least half a year) before the directory-thing was implemented.
