There's also an intro mentioning him, plus a big photo of him, and he's listed in the topics. But I think you're substantially right: the article text proper doesn't mention him at all... as if it's been link-baited by Salon, and the article authors are innocent. This makes it less annoying to read.

Spaced and varied learning is more effective - which fits with Gladwell's/Dweck's "deliberate practice"/growth mindset anyway.
