Haha ... funny to read about people scratching their head over Self. I feel like once you've wrapped your head around the Squeak version of Smalltalk, your about 50% of the way towards understanding Self. It's not a language the way we think of it, with CLI tools and syntax and text editors. It is a mutable environment of programmable objects. Sure there's some writing inside of objects to create methods, but you're not gonna find a "try this in the browser" code.
Self is/was http://noflojs.org/ 's grandfather.

I would also argue that Self is to programming languages what Haiku is to OS development. No on is writing a web framework in self, it's more of a toy and a neat artifact of where programming has been and could go in the future.
