I used Scrivener more like a generic [Outliner + DB] combo than a tool for long form writing.
IMO combining outlining and databases could be powerful if fully exploited (research...).
I truly consider Keith Blount to be a "hero" in the sense that he offered this power for all writers out there (at a reasonable price.)

FYI, Other outliner+DB beasts include the "overlooked for way too long" Infoqube [0] and the "probably soon to be a rising star" Tana [1].
