It's probably a good thing I'm not rich*, because all I'd spend my money on would be things like, say, Glue, the Steven Soderbergh novel that he originally published on Twitter and is now selling in an ultra-rare hardcover edition. As Soderbergh notes,
What you’ve really wanted all along was a signed hardcover copy of Glue, and as you can tell from projects like Full Frontal and K Street, I’m all about giving people what they want.
I might not spend $65 on the book, but I am sorely tempted to pick up a whole bunch of other stuff (particularly those Haywire and Solaris tags). Thanks to Bleeding Cool for the heads up—they've also got a link where you can read Glue in its entirety.
*No it's not. It's a terrible thing.
