I've been a professional tech writer for 26 years now. Have worked for Nortel, Sony & other Fortune 500s along with many technical web sites (many, MANY web dev sites.) Also have worked with video training sites: had to write code samples in so many languages that I actually had to learn enough of several to write the samples. What other tech writer picks up a new language to write a class to teach that language? AND makes the students laugh. Almost doubles his traffic - had to be a first. Students copied and pasted those samples everywhere :)
