What I'm really interested in is why this is so popular now. Clicking on the name-next-to-the-title it looks like this is the 6th time it's been posted. The other posts got 13 points _total_, and this one is now at 130-ish.
Does anyone have any links to articles about how sites like HackerNews and/or Reddit get gamed? Any ideas about good keywords to put into a Google search to find info about this?
If this is interesting, you may also appreciate the cousin of this book written for Common Lisp: Land of Lisp (http://landoflisp.com/?ref=nf/)!
It has an amusing sample chapter to see what you're getting into.
