New Sections Redux: Halls of Fame and Shame

Well, that was quick!

After updating several reviews and grades, the combined Hall of Fame & Shame got too unwieldy to update and navigate very quickly! So it's now been split into two: the Hall of Fame gives you quick links to the highest-rated materials that have been reviewed, and the Hall of Shame gives you an easy way to find the reviews where I most needed a drink.

That'll teach me to be lazy and think one section will do when it ought to be two.
