The document discusses how companies can crowdsource content and technical documentation by leveraging their "in-crowd" of employees, customers, partners, and experts. It recommends implementing a collaborative knowledge base (CKB) using MindTouch's open source platform to attract new knowledge and perspectives in a cost-effective way. By engaging the in-crowd through a CKB, companies can foster innovation, produce documentation at a lower cost than internal teams, and build stronger relationships with stakeholders.
