A Knowledge Drill Down (KDD) offers a quick and easily updatable way to order and present information.

A KDD encourages the layout of information hierarchically, presenting a basic overview first and allowing the reader to pick which parts to investigate further, which bits to drill-down to, increasing detail whilst maintaining focus.

For an editor, a KDD allows a quick and easy way to get information onto the web and to keep it up to date in a similar way to a wiki but with much less complexity. Unlike a wiki, layout is much less configurable. KDD is all about the content.
