Which chefs should you follow on Twitter?

While the actual use of Twitter has yet to be uncovered, it can be as valuable a time suck as YouTube given the right search parameters and some interesting people to follow. So Fat City jumped into the Twitterverse to find out which chefs are worthy of the time you devote to procrastination.
The criteria were simple. The authors all had to be chefs. The tweets had to feel like they were being written by the author. And they had to be interesting for at least consecutive days. Here are our recommendations:
Grant Achatz — owner and chef at Alinea in Chicago. He tends to have quirky observations about diners, life in the kitchen and what he’s cooking.
Christopher Kimball — the founder of America’s Test Kitchen on PBS. It’s like Bob Vila on Twitter. With recipes and kitchen tips, this is easily the most useful Twitter account in the food universe.
