apparently someone thought that the notion of a tag system with a semantic scope bound to a file tree hierarchy is such a ridiculous--nay, offensive!--idea that they had to downvote me for it, but couldn't bother to address it on the merits. The problem I see with tag based structures is that tags are global in scope, and so, tags have to mean one thing and one thing only; on the other hand, having one set of tags for a photo directory subtree, and another for my code repository makes a hell of a lot of sense to me.
