What Do You Read About

I've been keeping track of what I've been reading* for over six years now, but the other day, I figured I might as well visualize the topics via a tag cloud. Well, here are the results! I have each term weighted by the length of the book. Weighting by number of books seems to skew the cloud towards the more generic terms, which, to me, makes it less interesting. A live version is available on the reading log, but I imagine it won't change very rapidly.

Please note that I had to take out terms like fiction, non-fiction, sci-fi, and fantasy as all books are tagged with at least one of those.
