The early bird discount for registration at FM's Conversational Marketing Summit ends Weds, so if any of you are thinking about joining us in San Francisco this September, now is the time to register.

Please do RSVP soon, because our capacity at the Golden Gate Club is limited. We'll have to cut off registration for both the public and VIPs once we hit capacity, and that's at about 300 or so. We're already at nearly 200. And man, if you care about the future of marketing, check out who's joining this conversation (note that Google's new VP of Marketing, David Lawee, is going to be there):
