I've been writing a good deal about the sorry state of hypertext criticism lately. For the convenience of those just joining us, I've collected the key notes on The Criticism Page.
This is a nice example of how Tinderbox lets you improvise information architecture to meet changing needs. The Criticism Page is an agent; it scans a new attribute "topic" for items I've stamped as relevant to criticism. This adds a flexible category system to my weblog. It took only ten minutes or so to implement, and works the way I want it to. (For example, the oldest item on the Criticism Page is sorted to the top; this is the opposite of the usual weblog convention but it may help newcomers get up to speed without feeling like they've walked into the middle of the play)
