Inspiring read. I especially like the anticipated 'how' question at the end. This encourages me to trial and error my own elevator pitch.
Interesting to see how the pitch improved when the explicit problem statement and value proposition were dropped. Those are instead implied in the single-sentence pitch, which I guess partly is what prompts the "How?" question.
I initially read the domain as "emergent tone"...I thought it was a single-serving site about this topic!
