Good advice. One of the things I suffer from is speaking too fast, and yet to find a good solution for it. I put a sticky note on my screen reminding me to slow down these days, but it only helps so much. Another comprehensive guide for tech-speakers is https://speaking.io/ by Zach Holman.
Do you think one's tendency to speak faster originates from listening to podcasts at 2.x+ speed?
It's as though the natural state of the machines and tech is so fast, that we're trying to keep the information transmission as dense as possible so we can end the call.
Side note, I was watching an interview with Cory Doctorow and because of the tv segment style, both he and the interviewer were BLASTING through their talking points.
I wonder how much of our speech is being affected by the "say as much as you can before commercial break" model.
