This is Tedd's modus operandi. His website(s) are full of exactly this
type of thing. And I have to agree. I can't count the number of
questions I *haven't* asked on this list, because I built a page to test
a particular concept. And this sort of activity (as opposed to just
reading about something) really locks in your understanding of a
concept.
