There are a lot of great things about being a Drupal Trainer. My favorite is getting to see -- first hand -- how the code we write affects the community. I noticed that with the release of Drupal 7 - the demand for training on theme development increased dramatically. It took me a while to figure out why - exactly - but after a night of heated Debate in IRC with chx, mikey_p, HedgeMage, heyrocker, and yoroy (among others) we may have arrived at a conclusion. Chx pointed out that the best Drupal themes are made by developers - people who know Drupal really well, and understand all the code. Even though he is probably right (and most of the themers we have at Chapter Three really are developers, too) I have always seen the theme as the entry point for people who are new to Drupal.
