““The domain namespace is chaotic—every top-level domain and registry seems to have its own rules for things like minimum character lengths for domains, whether or not you can register at the top level (foo.nr vs. foo.com.nr for example)—and I didn’t want to go compile all these nuances by hand. So I used Mechanical Turk to gather things like the min-char lengths for each top-level domain, top-level registration possibilities, and all the second-level domains they may or may not use (Brazil is the craziest).””
