I've been Smalltalking since '94, in a business context (using VSE). A friend (David Brown, in fact) mentioned Squeak, and I'm very grateful for that.
I am currently working in a DBA type position, and only code Smalltalk in my free time, now using Squeak.
For some current snippets of my goodies, you can look at [http://nest.swiki.net/1] (Didn't work 2004-03-07). When these become polished enough for release, I'll announce them elsewhere - probably on this site or on the squeak list.
