Webz Earlier in the course?

[acbart]

Discussing with Katie and Deb, it really feels like we could be introducing Webz earlier in the course, and get more mileage out of it. At the very least, it could be used in more in-class examples with a lot of scaffolding. But I wonder if we could also scaffold it earlier in the textbook, with just a little bit of hand-waving? We need to examine what that would look like, and analyze the trade-offs some more.
