 ## Does Koa replace Express?
 
-  No, it's more like Connect.
+  It's more like Connect, but a lot of the Express goodies
+  were moved to the middleware level in Koa to help form
+  a stronger foundation. This makes middleware more enjoyable
+  and less error-prone to write.
 
 ## Does Koa replace Connect?
 
   No, just a different take on similar functionality
   now that generators allow us to write code with less
-  callbacks. Connect is equally capable, and some may still prefer it.
-
-## Why does Koa have functionality similar to Express?
-
-  Many of the Express request/response methods have been moved to Koa because
-  they are more useful at the middleware level. If you make the edges smart,
-  the intermediaries can do less and become more dumb, this reduces and conflicts
-  when middleware constantly attempt to re-invent the same behaviours such as parsing
-  signed cookies.
-
-  Additionally it makes writing middleware and applications more enjoyable, when the
-  mundane every-day HTTP work is less in your face.
-
-  Finally certain behaviours such as signed cookie secret management, and upstream
-  HTTPS proxy authorization benift greatly from app-level control. Configuring these
-  for each end-point would be extremely annoying and error-prone.
