I've done some presentations/demos in front of smallish audiences (dozens of people) but now I need to give a talk in front of 2000 people (+ probably live streaming). I'm scared, clueless, don't know where to start & I'm reaching out to HN: any tips? The talk is in 2 weeks.
Edit: It's an Ignite! Talk (http://igniteshow.com/). 5 minutes. 20 slides. 15 seconds per slide. auto-forward is on. Not sure if I can disclose the topic yet, will update when I can.
