Craigslist, Inc

Are you building a business -- or thinking of starting one? Especially if you're a corporate army of one, it pays to be in the "you" business.

That means promoting yourself and telling people what you can do as a potential goods or services provider -- or an employee, for that matter.

And increasingly the online world is the place to hang your shingle with dedicated Web pages and social-networking sites like Facebook, MySpace and LinkedIn.

One of the easiest and best ways to market yourself or your business is by creating a blog.

Under the watchful eye of law enforcement in 40 states, Craigslist pledged Thursday to crack down on ads for prostitution on its Web sites.

As part of Craigslist's agreement with attorneys general around the country, anyone who posts an "erotic services" ad will be required to provide a working phone number and pay a fee with a valid credit card. The Web site will provide that information to law enforcement if subpoenaed.
