Some pretty good stuff. He seems like quite the prescriptivist, but I love his Puerto Rican perspective, and I'm a sucker for stuff like the difference between "eficiente" and "eficaz" or why "estoy media cansada" isn't correct.

Enjoy and please share if you know of anything similar for other languages!
