What a fun day! There was a little confusion in the scheduling, but everything worked out well.
It does appear some people interpreted the schedule to have me presenting the same thing twice, once in the morning and once in the afternoon. I was under the impression that I was presenting once all day. As it turns out my content was just enough to fill up the morning and I was available and able to present it again in the afternoon. In total I had about thirty people attend my presentation Building Great Web Experiences For All.
