I think the headline here is somewhat misleading, based on the other responses thus far. It's not intending to teach web development using Seaside as the tool; rather, it's a tutorial on how to develop Seaside web apps. And while the fact that it's presented in PDFs is a little bit annoying, I'm about halfway through the tutorials and they're rather well written and expose a lot of features in Seaside and Smalltalk as a whole. As far as "zero to being able to make something interesting" guides go, this is one of the better ones I've encountered.
