When Phoebe Ayers isn’t hanging out at ROFLcon she’s probably doing something related to Wikipedia, so I’m looking forward to reading How Wikipedia Works: And How You Can Be a Part of It.
Extra points: Phoebe and her co-authors somehow convinced their publisher to release the entire work under the GFDL, the same license Wikipedia uses. You could read the entire thing online for free, but that’s the easy part. What will you do to return the value? (Remember, Andrew Keen is watching.)
