"Introducing BackType, a service that I believe, is navigating conversations back to the blogosphere.
BackType is a new service that brings blog post comments back into the spotlight. Whether you're managing an online reputation management (ORM) or an online monitoring system (OMS), BackType allows you to search keywords across the blogosphere to uncover important conversations that may require our participation, or at the very least, provide you with insight into critical community perspective. You can also search all comments by a particular person and date range to create a snapshot of someone's area of focus, bias, or expertise."
