Clutter and confusion are failures of design, not attributes of information.
I recently wondered, “what is TEI used for?” I have known about TEI for about three years but somehow its purpose slipped my mind. (There is a basic introduction to TEI here.) All I could remember was that it took a lot of time. When I looked back at my dissertation (where I had wrote a little about it in relation to the Rossetti Archive), I could not remember much more about it than it was used as a structuring element for the massive amounts of information housed in the Rossetti Archive. After a quick Google search, asking the same question, I came up with an answer.
