I unexpectedly saw this article on learning vocabulary and found it quite interesting. I especially like his notion that "reading in Chinese can, in a sense, improve your English." I heartfeltly agree on this. On the other hand I am encouraged to have found quite some words the author (who I assume a native English speaker) was learning in college that I already know. This article also points out for me an online version of the American Heritage, which is nice.
I have been taking an approach to vocabulary quite different from this author. I'm thinking about trying out his though.
