Doesnt gopher sound a LOT like opml? Opml makes little user-created islands of hierarchical order out of the chaos of the Web, at least for those cases where such a structural ordering makes sense. Thats why yahoos taxonomy ruled supreme in the early days, the intentional design of the information spaces hierarchy to fit the subject by a human.
Opml lets this be done by individuals, where ever it makes sense to, and rss lets us move time ordered data around, including versioning information about opml hierarchies, either through an updated entry in an rss feed containing the link to the new version or indeed wholesale transport of updated versions via sending an entire opml document down an rss feed!!
