Talk like TED: Die 9 Geheimnisse der weltbesten Redner

I'm curious how Carmine Gallo chose TED presentations specifically and whether he believes their style is universally effective.

The emphasis on storytelling in public speaking made me think about how I could better craft my own talks. Has anyone tried these techniques yet?

With more talks happening online, I'm wondering if the principles in this book hold up or need adaptation for a digital audience.
