I just read the TechCrunch post announcing that a new service called Ether that is launching tonight. The concept is simple, setup an account and you get a phone number where people can call you for advice. You set the per minute or per hour rate for the service and Ether takes 15% off the top. In addition, you can sell your digital content.
What an amazing idea. If people are willing to pay for it, anyone can earn some extra cash by sharing some immediate knowledge or content without any overhead in setup. If only I could use this when my relatives call for computer help :)
