From Nina Paley’s blog:
I was neither prepared nor in a particularly good mood when I did this “webinar” for Agora I/O. It was eerie having a “conversation” in which I could neither see nor hear the other participants. It was just me and my own voice, with questions and comments occasionally popping up in text on another webpage. Because of that, I couldn’t read anyone’s body language and try to pre-emptively smooth things over and “people please”; I could only speak my mind. Which I did. Which, upon reviewing, was a pretty great thing. You may not like me, but I sure do!
