Oh and if you want to build a fancy webapp with Smalltalk check out the Seaside framework. After hearing a podcast with the creator Avi Bryant I took a quick look at it and was really impressed. Dabble DB uses Seaside and after seeing their demo movie I must admit that you can build really impressive applications with it. There is a nice beginner tutorial here.
