I agree with your summary. My enthusiasm for VFP, espeically the new version 9.0, is the same as it has always been. Most of my presentations now are more formal as you say. I have done regular technical sessions like in Frankfurt and Sydney in the past few months, and I did show things saying "Hey, this is cool..." during demos. In recent years, I try to do presentations and demos that are more clear and understanding to the entire audience rather than on cool technical things that sometimes are a bit random or fast like I did years ago. If I talk slower or more serious, it is because I'm focused on clarity and it doesn't mean I am less enthusiastic. :)
