12 people feels quite a crowd. From my experience talks in crowds of that size stay typically very shallow. Any ideas on how to keep that more focused?
well, 12 is the absolute maximum, i personally prefer a number close to 10. something which has worked quite well so far is a short introduction of yourself and the idea behind the dinner when everybody has arrived. then hand out some notes with the three rules on it. lead by example ;)
if you're low on cash, do pizza and beer at a brewery or the like. the gesture will be appreciated virtually no matter the venue.
Not everyone can afford a meal out for 12, even at what you consider a cheap restaurant.
