Andrew Nelson, a writer for National Geographic Traveler, recently came to visit Miami. He used Twitter as his guide to the city, soliciting suggestions on sites to see, hotels to rest his head, and places to get his grub on. I was one of about a dozen people who assisted him with recommendations on his trip and I had the chance to meet up with him before he skipped town. Andrew is a real nice guy and wrote about his experience with Twitter and the city of Miami here. It's really cool to see technology involved in enhancing one's travel experience. Andrew got to see Miami in a way that most visitors do not, beyond the sexiness of South Beach and into the worldly neighborhoods that make up this city. Check it out sometime. It's a great read.
