I gave my talk. I was more than a little dazed while I gave it, but it seemed to go well. Most of my audience was still there at the end, and they were still alive enough to laugh in the right places.
I won't really know how it went until I get my feedback in a couple of weeks.
Ideally this would be the time when I could sit back and enjoy the conference. Unfortunately child care responsibilities made me come home after one day so I'll miss it. However in a short time I saw a lot of familiar faces (eg Schwern, Robert Spiers, Damian, merlyn, etc) and met some interesting people (eg I had lunch with the CTO of Wikipedia). Plus I enjoyed Damian's talk on scripting vim. (Tip: Do not let him near your vim configuration anywhere near April 1. Just..don't.)
For those who are interested, my slides are online. I still have a couple of edits to make (mainly that I want to put in some of the actual questions I was asked), and it should be posted on the OSCON site some time this week.
