Thanks to all your proofreading, we have a version of my book online with about 800 fixes of problems of the first version. (Although about 500 involved curly quotes, em dashes, and other things that are hard to notice on screen, but look bad in print.) A couple of hundred more involved one letter typos that are particularly hard to fix. But that still leaves about 100 lulus fixed, such as getting maternal and paternal grandparents confuses, which is kind of show stopper with Barack Obama.
You can read it online here.
I'll try to send up a system for wiki proofreading tonight.
We're sending it off to the printer tomorrow, so soon you'll be able to buy an actual physical book to give everybody you know (perhaps especially the people you don't want to know anymore).
By the way, the counter shows only the number of zip files downloaded (currently 2600+). I imagine most people prefer to read it online, so total readership is probably a few times higher.
