Randy Coulman is doing some great work in terms of getting Smalltalk noticed outside of its traditional realms:

For now, I've added some information about the Smalltalk version of Fit et al at www.fitnesse.info, which is a community wiki that was set up to discuss Fit and Fitnesse.  I've also added the necessary example code for the Fixture Gallery that is available from the same site.  The code is shown in classic fileout format in the documentation. 

This is the second integration like this that Randy's done; he's also gotten the Smalltalk code for integration with CruiseControl accepted into that codebase.
