Choosing a babysitter is one of the most important decisions you'll make as a parent.
Genevieve Thiers, who put herself through college by babysitting, has put the Internet to work helping parents. Her site, Sittercity.com, is a database of more than 100,000 babysitters. It has profiles, references, customer ratings of sitters, and information on how to screen and interview sitters. "It makes finding a sitter easier and safer than before," she says.
