Thanks for the super prompt replies Henneke.
One more question:
The two headlines, which you came up with, that I like:
“How the Khan Academy Boosts Learning Using 4 Montessori Principles
How a World-Famous Online Academy Boosts Learning Using 4 Montessori Principles”
Did you actually use a template from Headline Hacks or someplace? Or was it just intuition after years of coming up with headlines (with or without templates)?
