Don Briggs: SuiteModeler
Don Briggs' experience with Cocoa (NeXTStep/OpenStep/Rhapsody) goes way, way back. Don and I occupied the two leftmost seats of the front row during the Programming WebObjects I training course in March of 1999. I thorougly enjoyed his company over those 5 days.
It's cool to see veterans embracing Apple technologies like AppleScript and making cool apps.
