Also, FYI: `console` is undefined in Internet Explorer *unless* the dev tools are open, in which case it is defined. Super confusing. According to [this StackOverflow question](http://stackoverflow.com/questions/5472938/does-ie9-support-console-log-and-is-it-a-real-function), this is still the case even as recent as IE9, which we do support. (We don't support IE6.)
