LinkedIn's announcement of a $175 million IPO has reignited the debate around whether hugely successful internet companies should go public. LinkedIn is one of the largest professional networking sites and is poised for a blockbuster IPO after tripling its revenue between 2007-2009. While LinkedIn would not be the first internet company to IPO recently, its size and success in social networking means its IPO could have significant ripple effects on other major internet companies considering going public. However, there are also risks to consider for internet companies in taking the plunge to go public, including loss of focus, increased scrutiny, and potential loss of control.
