Mark Cuban invests in new journalism Web site

Entrepreneur billionaire Mark Cuban has invested in a new journalism site focused on exposing corporate fraud.

Sharesleuth.com, the brainchild of veteran St. Louis Post-Dispatch reporter Chris Carey, is expected to go live next month.

"It will be a blog-style news operation dedicated to exposing securities fraud and corporate malfeasance. We're going to identify questionable companies and tell compelling, deeply researched stories about the people behind them," Carey told CNET News.com in an e-mail on Wednesday. Carey will serve as the editor and president of Sharesleuth.com.
