Scoop has sections and topics.

Sections include Diaries, News, Indices and Debates. Only Frontpagers can post things other than Diaries (called "Stories"), but that can be changed with a clich of a mouse, so it is open to debate. New sections can be created. They can also be eliminated and all the existing content added to a existing section. Sections can be nested. Right now they are all top-level but they needn't be.

Topics are selected in the story/diary edit form. They include Everything, Diary, Economy, Energy, ET Community, Europe, International, PDB and USA. Topics can be added or eliminated as well. I believe PDB is an old occasional series written by soj back when they were a frontpager.

People could select an appropriate Topic for their diaries or we FPers could do it. This way of classifying content has been superseded by tags in more modern blogging practice, but that's the way SCOOP works.

Boxes can be made to display the latest N stories in any topic/section. A box could also be created with links to the various sections or topics.
