It's a good case study in market segmentation, though. Lisp works because all of the programmers who would like to do language design as part of their day job gravitate to it. As a result, it has the most advanced language features of any language on the planet. All of the programmers who just want their programming language to be a stable, dependable tool they can use gravitate to other languages (tops among them: Java and Go), and they build some pretty cool products with them because they aren't distracted by improving the language. Wasabi's big failing is that it tried to introduce Lisp-like concepts to programmers who have to work in ASP and PHP in their daily jobs. It's kind of a no-man's land there.
