On the back page of Denny's dinner menus, there's a "Join the conversation!" section that implores diners to follow Denny's on Twitter at twitter.com/dennys. Thing is, that's the Twitter feed of a Taiwanese man named Dennys Hsieh.
Denny's real Twitterfeed is http://twitter.com/DennysAllnightr. More than 7,000 people have been able to figure out the difference.
