If you own a small business that relies on foot traffic, embrace Buzz immediately. You can broadcast the availability of specials or sales. You can even use the real-time nature of Buzz to implement flex pricing. Too many loaves of bread, empty theater seats or other perishable items? Cut the price and broadcast the sale. People nearby will see it and come running. In addition to selling to existing customers, you'll win new ones.

I believe my fellow tech pundits will truly "get" the power of mobile Buzz at the next major IT industry event. Here's what will happen: The early adopters will start an invisible, back-channel, ad-hoc social network during the show based only on GPS location. In other words, people won't need to know the URL for the official message board or chat room. They'll just use Buzz's "Nearby" mode, and everybody nearby will be a conference attendee.

People will introduce themselves to fellow attendees by broadcasting their Google Profiles page -- a kind of "business card exchange." A few speakers will draw crowds by promoting their presentations on Buzz. Attendees will arrange meet-ups. The people on Buzz will get more out of the conference.

At the IT industry conference after that one, nearly everyone will be using Buzz. From there, it will spread to non-tech conferences. Within a year, I think Buzz will become the de facto source of information and networking at all industry events.
