There were 2 recent FileMaker user group "game show" meetings that went very well. (links below)
Different people would take sides and duel over a particular FileMaker topic.
The audience would join the debate and everyone would then vote.
With the disclaimer that, in most cases the correct answer is “it depends”, the game show format led to lot of interesting and fun discussions.
Here are outlines of the  meetings...
