Should you share your business ideas?

Seth Godin's latest project ChangeThis presents several manifestos.

Guy Kawasaki talks about how to start a new business. Do you share your business ideas with your dog and no one else? That could be a problem on a couple fronts, according to Guy.

The only thing worse than a paranoid entrepreneur is a paranoid entrepreneur who talks to his dog. There is much more to gain -- feedback, connections, opened doors -- by freely discussing your idea than there is to lose. If simply discussing your idea makes it indefensible, you don't have much of an idea in the first place.

We've all heard of people so afraid of losing their business idea that they produce a 40-page nondisclosure agreement -- and then ask you to read it.

Dallas Morning News columnist Cheryl Hall writes of a business woman who takes a different approach. Karen Shelton freely shares her wisdom -- even with competitors.

You see, she believes her passion and energy creates the business advantage.
