It is all the same crap, just repackaged. In the mid-90s I had a portfolio of about 10 talks. Most followed a standard formula. I remember going out of town once to give a talk and realized I brought the wrong outline with me. I gave the talk and no one noticed (or cared).
If they have changed it is because of the shortening of time. Aren't public talks now 25 minutes. I think the talks I gave were 45 minutes.
