Although I do not do any Smalltalk myself yet I was interested in knowing about Seaside which, according to the official website, is "a framework for developing sophisticated web applications in Smalltalk."
What interested me most was that the developers of Seaside boldly stated that their framework is breaking with common accepted best practices in web development. Usually a new framework tries to use all sorts of buzz words and tell you it conforms with all widespread as well as new best practices, yet finding a framework that is bold enough to state upfront that it is breaking with common accepted best practices is something that would attract my attention. I'll try to learn more about Seaside, not in order to develop web applications with Smalltalk, but perhaps to learn some concepts on which that framework is build hopefully to carry them over to other languages which I do use.
