I know I need to get better about using #hashtags but you have to understand I was traumatized by discussions about #hashtags and #folksonomies during #LibrarySchool

The dissertation of @publicvoit on TagTrees, while interesting in its own right, also has a very interesting overview of historical #PIM #HCI research:

Oddly, though, even though it focuses on organizing personal information including files using free-form tags, and even talks about photo management and bookmark management as application areas, it doesn't mention Indecks cards (or other edge-notched cards), Lotus Agenda, or Flickr. It does mention del.icio.us once in passing on p. 67.

The TagTrees method he proposes doesn't rely on organizing the tags themselves in a tree (like Agenda). Rather, the #tags in a TagTrees path are intersected without any concern for their order; the tree view is just an "associative browsing" affordance.
