Actually, let me qualify that: I love data that you can do creative things with. I don't think I could quite cope with being a statistician (I think you need a basic level of maths for that), but I love seeing patterns in data and comparing lists and stuff like that. So I'm a nerd, I get it.

Next is to tackle my home library, which is no mean feat. But it will be nice to see what I own and how it compares to what other people own. As well as the standard 'suggester' (along the lines of "if you loved ... you'll also love ...") LibraryThing has this nifty 'unsuggester' feature. It takes a book you have read/own and tells you what you are least likely to have also read, based on the data in its vast database.
But I confounded it when I entered Margaret Atwood's The Handmaid's Tale and was told I was least likely to have read The Passion of Jesus Christ by John Piper. I've read (and enjoyed) them both. In fact, most of the books I've entered (by Pratchett and Gaiman, as testers) have returned results that are mostly Christian books - if I haven't read them I'm at least familiar with them.
Not only am I a nerd, I'm an anomaly!!!
