If you think about the tribes you belong to, most of them are side effects of experiences you had doing something slightly unrelated. We have friends from that summer we worked together on the fishing boat, or a network of people from college or sunday school. There's also that circle of people we connected with on a killer project at work a few years go.
These tribes of people are arguably a more valuable creation than the fish that were caught or the physics that were learned, right?
And yet, most of the time we don't see the obvious opportunity–if you intentionally create the connections, you'll get more of them, and better ones too. If the hallway conversations at a convention are worth more than the sessions, why not have more and better hallways?
What would happen if trade shows devoted half a day to 'projects'? Put multi-disciplinary teams of ten people together and give them three hours to create something of value. The esprit de corps created by a bunch of strangers under time pressure in a public competition would last for decades. The community is worth more than the project.
The challenge is to look at the rituals and events in your organization (freshman orientation or weekly status meetings or online forums) and figure out how amplify the real reason they exist even if it means abandoning some of the time-honored tasks you've embraced. Going around in a circle saying everyone's name doesn't build a tribe. But neither does sitting through a boring powerpoint. Working side by side doing something that matters under adverse conditions… that's what we need.
