Gather at 7:00. Starting at 7:15, anyone who feels the urge gets 60 seconds to sound off on her or his latest cause. When the bell rings, sit down, shut up, and listen to the next person. After about 10 minutes, we've got something to talk about and can spend the next couple of hours doing it.
To prime the pump as to what to talk about, I will be doing a dramatic reading of all 51 root words in the English language containing the character string "ugh", and I'll be pronouncing them as God originally intended.
