Mark Cuban did exactly this, but never fixed the "bugs." He sold Broadcast.com to Yahoo (when their stock price was near $400) for billions, and I spoke with the Yahoo Dallas SVP tasked with integrating it back in 2000. He said it was useless and unworkable and Yahoo shuttered it 6 months later - an event that started the stock's downfall. Cuban is a total fraud. All his subsequent startups have failed, including one HDTV channel in which he ridiculously brought on another fraudster, Dan Rather as head of "news."
Old Twitter and Facebook and Google all are stock fraudsters.
