Twitter founder Jack Dorsey announced his latest venture, a company called Square. As an attempt to solve many of the key issues associated with accepting online payments, Square promises a refreshingly simple system for cutting through the red tape.

In February 2009, Jim McKelvey wasn’t able to sell a piece of his glass artbecause he couldn’t accept a credit card as payment.
