I recently put something very like BookShout on my idea list... basically just shareable, public, user-created lists of reference materials (books, websites, whatever). Looks like I don't have to build it anymore. =P (My personal pain point was finding ordered lists of materials -- taking you from beginner to at least intermediate, produced by someone who knows what they're doing. Fingers crossed that BookShout will expand in that direction.)
