We did this in SF a week or so ago and it turned out beautifully. About 12 of us ended up in a coffee shop/bakery sort of thing. I wasn't sure we would find something to talk about. (I just knew I didn't want it to be me.) We had a lively time. We just rambled and it was fun.
There is another possibility. If someone has a hall (or a big room of any kind, really), I would be happy to do my slide show on the Chief Culture Officer argument. That's before and after we chat over coffee, that is. (It's official. I've become a shill machine and will remain so for the next 6 weeks.)
Let me know if you are interested in either eventuality. Send an email to me at email@example.com.
