We had a pretty good turnout on the night (possibly boosted by the presence of my wife's chocolate brownies). The audience was exactly what I'd hoped for - a nice mix of seasoned developers and non-techies. I wanted everyone to follow along so I started with the basics of what JS is, and what it's used for. Then covered the early days of the web and on through it's evolution into the "glue of the internet".
The slides went through about five revisions (as these things do) and much of that was due to the great feedback I had from presenting early drafts to David Rosam and my eight year old daughter. Thank you both.
