Ted Leung spots the Croquet talk from last year, and has a few thoughts on it. It's worth reading the whole thing - he mentions a number of good kay comments. I found this comment at the end of Ted's post interesting:
Much as I love Lisp, it seems to me that the Smalltalk community, led by folks like Kay, are continuing to demonstrate a convincing agenda for forward progress, while the Lisp community is perennially struggling with basic infrastructure issues like which dialect of Lisp/Scheme, which windowing environment, etc. Perhaps this is due to the conception of Smalltalk as a system, in addition to a language.
