Can we have a TL;DR from somebody who knows what this fella is talking about? I've spent 15 minutes on the page trying to get the gist of it, but feels like a sequential collection of scattered thoughts rendered on a webpage without having been reorganised for somebody else to read. I get that it's about a technique for fast learning a foreign language, but I don't want to have to read it in its entirety to make my mind if it's a great idea or just some crazy ramblings. Given the layout of the page, I suspect it's more of the latter...
