No, this isn't a David Letterman post.I got a message yesterday that my MonoTouch ebook is #5 in the Amazon.com sales list for ebooks. I'm not sure what that quite means or how its calculated, but I assume that this is good. It looks like the results are recalculated, so I could be #1 or #1,000 at any time. Either way, I think that this is cool.
On a separate, but related note, my friend Michael Neel's XNA ebook is right around the same spot. Congratulations to Michael.
