The John Piper Unsuggester Game!
Nifty little thing, this.

Basically, the Unsuggester tells you what books LibraryThing users who liked a particular book didn't like. The works of John Piper (who's actually one of the few Baptist writers who haven't gone completely off the deep end) seem to appear a lot. Like links to the transhumanism page at Wikipedia.

So, this is the game. Pick a book, any book, and see how many links in the chain it takes before you run acriss a book with a John Piper work as its number 1 Unsuggestion (Double points if it's "Don't Waste Your Life"). Like so:

"High Fidelity" - Nick Hornby
"Systematic theology: an introduction to biblical doctrine" - Wayne Grudem
"The Bell Jar" - Sylvia Plath
Back to Systematic Theology, not a winner.

"Atlas Shrugged" - Ayn Rand
"Where's My Cow?" - Terry Pratchett
"Into Thin Air" - Jon Krakauer
"Briar's Book" - Tamora Pierce
"A Confederacy of Dunces" - John Kennedy Toole
"Boy Meets Girl: Say Hello To Courtship" - Joshua Harris
"Good Omens" - Terry Pratchett and Neil Gaiman
"The Passion of Jesus Christ" - John Piper

(I've read all of those besides the courtship book. Thank God that 19th Century throwback shit didn't become popular until after I got laid.)
