Crunchy Frog is cool! Must be, since even grouchy Arthur thinks so. To me the attraction is not so much "web-based" - at least any more than the attraction of something like html docs is that they are necessarily web-based - in the sense of Web as in Net, as in Remote. 127.0.0.1 is cool too. Don't think that the computer obsoletes text as the primary vehicle for learning. And it seems pretty clear that reading straight text documents via computer has *disadvantages* over the dead tree approach. And in fact most web based interactive learning efforts I have seen seem lame to me. See Not Pi. http://www.sock-monkey.com/pi.html I do not see too much more than that in javascript turtles that folks seem to find so exciting. But I, and most everybody else, appreciate the fact that hyperlink technology for documentation - as an example -can add a level of truly useful functionality to text documents. Seeing Crunchy embedded in, and extending, a substantive text document as in the Crunchy .7 mini-howto helps me understand and appreciate its usefulness in extending text documents. Here, existing "how to" docs were extended with Crunchy. If they were written from scratch with embedded Crunchy they might have taken a slightly different approach. Might be a while before the possibilities here get appropriately shaped. Why is all the cool stuff being done by us "hobbyists"? Art.
