I never used smalltalk until last semester. Once I got over the hurdle of the syntax I could see that this was a powerful language. Since I already knew smalltalk before reading this chapter, I didn't get anything out of the parts that talked about the syntax of smalltalk. I see a little benefit of discussing the syntax in the context of the structure of the language, but it seems to me that this part would be better off in a section to teach smalltalk. The paper just did too much on this part.
One of the main things about Smalltalk is that everything is an object and they just send messages to each other to communicate. Java also uses this line of thinking but does not go to the extent that Smalltalk does. Java does have primitive types that are not objects, but those primitives can be encapsulated into Objects (Integer holding a primitive int for example).
