Small suggestion: Post some code examples easily accessible from the main page! I've checked the documentation, the dylan book, the "get started".. I still have no idea what Dylan looks like. Basically, a quick "Dylan in 5mins" tour to give me a taste of the neat features.. so it gives me a reason to digg further in the doc.
I should've thought of this earlier, but we have an entire book online (although it hasn't yet been converted to our new documentation / publishing format): http://opendylan.org/books/dpg/db_1.html
