Having personally received and dismissed so many email invites to seminars and talks I became worried that an invitation to my own presentation might go unnoticed.
Additionally I was concerned that those who did RSVP would never find the room the day of because it was in an out of the way location.
My solution: a video to demonstrate how to get to the room and personally relate my topic with the tone and inflection that email would otherwise strip away.
With iPhone in hand I set out to nail this in one take!
