I must admit that although I have a Twitter handle, it has been months since I tweeted about anything. Really, who cares? So much personal tweeting is navel-gazing at its most trivial. However, Twitter does serve humanity in one great way: letting us know where favorite food trucks will be at any given time. We've compiled a list of notable such twitterers for BusinessBalance.com. The information is particularly useful for travelers in a strange town looking for a food truck with no permanent address.
