I saw a live version of this when I was a grad student (not the original talk at OOPSLA, but he re-gave it a lot at some universities). It was fascinating to see what could be done with hand drawn transparencies; you have to give GLS lots of style points!
The 'e' thing was just a temporary typo by a moderator. The title change was presumably because "presentation by" is redundant (and not in the original).
But mostly we take the author's/presenter's name out of titles, in keeping with HN's focus on content over personalities.
