They fall between the cracks of "serious" study of algorithms and data structures, and user interface and user experience (which still is not much-studied, but at least is starting). This is more the history of software. Much like the history of film, or the history of rock and roll.' So, Dave asks, what early software was influential and worthy of a Software Hall of Fame?"
