I had a quick read about WARS the other day, but haven't spent much time thinking about it yet. Basically (crudely) it's an 'MVC like' pattern.
I liked this quote from the article: “breaking down complex systems into families of interfaces is something we should at least attempt“ and this one: “A correct approach would be to create a new hypothetical style that describes best practices already used in the problem space, instead of prescribing an architectural style from a distantly related problem space“, oh stuff it, the whole article is good, just read it. :)
