I subscribe to the opinion that the more you know, the more you realize you don't know.  This may sound strange for one still in high school, but I think my AP history and physics classes last year gave me a yearning to learn more, including a lust to expand my vocabulary.  This led me to embark on a Google search for a site that would do such, and I, somehow, ended up here.  I signed up, I believe in May of this year, during male-and-female-versions-of-words week.  I joined AWADtalk less than a week later.
Participating in this discussion board made me enter my AP English class with a whole new perspective.
