I think a better question would be, "Does anyone program in Smalltalk yet?" It seems to be becoming more popular, rather than less. As people begin to get an awareness of more advanced paradigms some of the older research languages begin to look nicer. Smalltalk is OOP done very well. Ruby is actually a lot like it, and may turn out to be a better Smalltalk than Smalltalk (some would say otherwise, of course).
