Having recently tried to get started with Squeak, I can say that it is hard for someone used to text editors, interpreters, and compilers to get used to the typical Smalltalk environment such as Squeak.
I get Smalltalk the language, but I don't get Squeak (which from what I understand is fairly typical as a Smalltalk environment). It'd be nice if there was some kind of guide like "Squeak and Smalltalk for those addicted to their text editors and command prompts." From some comments I see around, I think that I am not the only one with this mental block.
Good article nonetheless.
