Blogs don't just aid business, they become one

Putting on a show: Dennis Littley presenting his kitchen studio at his Kissimmee, Florida, home where he hosts a weekly, live cooking show online. Littley, a retired professional chef, is one of the many bloggers who are making it big for blogging about things they are passionate about.

Dennis Littley doesn't exactly like to prepare elaborate meals for himself. He'll usually get by on a sandwich or some eggs. 

But when the camera rolls in his makeshift home studio, the veteran chef – who has prepared food in executive suites, upscale restaurants and lunchroom cafeterias – comes alive.
