Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this one from Petr Stepanek:

Craft.CASE is a business process management tool written entirely in VisualWorks. This experience report will discuss the internal architecture of Craft.CASE, its metamodel, components etc. We will report on design and implementation issues, ease and difficulties we had with the implementation using VisualWorks Smalltalk and current state of development.
