Show HN: your very own horse_ebooks generator

As Buster Benson (of Twitter) mentioned on his blog (http://wayoftheduck.com/diy-horse-ebooks), @horse_ebooks was killed off yesterday. In response, he created a simple Ruby script that uses Markov Chains to generate @buster_ebooks, a version of @horse_ebooks made from his Tweet archive (https://gist.github.com/busterbenson/6695350). A script is cool, but what if you could have a gem? SAY NO MORE!
