Looking for something to read? Library Thing will let you go the usual Amazon route where things are recommended based on what you like. But, more interestingly, it will also let you type in a book you love and tell you what books you will hate based on that.
If one of your favorites is Immanuel Kant’s Critique of Pure Reason, it tells you that you will loathe Confessions of a Shopaholic. This is based on information about people’s actual bookshelves, so in the examples I typed in it was entirely accurate. Not to self: Never read Real Men Don’t Apologize by Jim Belushi, the internet tells me I would hate it. Well, that and common sense.
weirdly, i put in my favourite book (jane eyre) and all the unsuggestions were either based on questioning the church OR web design. both of which are things i like just as much as jane eyre. I BROKE IT!!
It has actually been very close for me. Most of the time it’s either books I would never read or books I’m embarassed I read as a teenager.
I think, being a geeky site, it is heavily weighted toward atheists like most things nerd.
