this week Nikolas Martens (https://twitter.com/rtens_) gave a presentation about Smalltalk at a Softwerkskammer Berlin event. He live-coded a TicTacToe game twice (in Morphic and Seaside).
There was a lot of interest in coming together more often to discuss Smalltalk and related technologies so he set up a "kick-off" meeting for the "Object Group Berlin" on Monday, June 12. If you are interested in attending, please RSVP at https://www.meetup.com/Object-Group-Berlin/events/239818819/
