Restaurant consultant John Bowler seemed an unlikely entrant into L.A.'s thriving food-truck scene, which depends largely on Twitter to let folks know where these mobile eateries park for the day. "I was not into the social-networking stuff," Bowler says. "I'm 64 years old. I got all the friends I can use."
But after trying Kogi, the pioneering Korean-Mexican barbecue-to-go that commands thousands of followers, Bowler turned to his college-age daughter. Once she taught him about the power of 140-character tweets and Facebook networking, Bowler was in business. His Barbie's Q southern-style barbecue truck is now one of some 100 twittering food trucks cruising greater Los Angeles. You can find movable feasts in many other cities, too. Go to seriouseats.com and search "twitter list."
