It's widely understood that new customer service channels such as social, email, knowledge bases and the like have left the service agent with harder problems to solve. Those channels are here to stay, because when they work well, they solve problems for pennies. It can cost many dollars to resolve an issue through the efforts of conventional agents. So there's a decided bias for self-service where possible. However, we need to ensure that there are graceful transitions from the channels to agents, or we risk a backlash.
