How would postsecondary profiles work? LinkedIn founder Reid Hoffman said a 21st century diploma, “Would accommodate a completely unbundled approach to education, allowing students to easily apply credits obtained from a wide range of sources, including internships, peer to peer learning, online classes, and more, to the same certification.” This “dynamic and upgradable” machine readable profile, “Should allow a person to convey the full scope of his or her skills and expertise with greater comprehensiveness and nuance, in part to enable better matching with jobs.” Hoffman obviously has interest in LinkedIn serving as the preferred market signaling platform.
