When I originally "designed" (I use the term loosely since evolved is more accurate) the system, "Sections" were meant to be for "Data Types"... for example "Book Reviews". A book review is fundamentally different than a Slashdot "Article" because it has extra fields like the ISBN code. At the same time I essentially coded "Skins" because each "Data Type" needed custom look & feel type stuff so that the story could actually display the unique data fields.
So when we created YRO and the BSD section and later on the Apple section, I just reused the skinning part of "Sections".. it was the easiest way to do it, but it created problems later: under the old design a story could only have one "Section"... some sections defined "Data Type" and others defined "Subject Matter" (like Apple or BSD)... thats why bsd.slashdot.org can never include a book review, and apple.slashdot.org can't include an 'Ask Slashdot'. This confounded users of our search page to no ends, to say nothing of frustrating editors who couldn't include topical stories within their appropriate section.
Undoubtedly we'll see some bugs to pop up... so please be patient and submit bug reports. We'll be wacking bugs for a few days... there's always a few of them that don't pop up until you put them in front of the half a million users on the real hardware. Thanks for understanding!
