Post-publication peer review is often discussed as an added aspect to traditional peer review process. Post-publication peer review can add value to published papers by increasing the number of reviewers, further developing discussion about the paper, and increasing the visibility of the paper to the public. For academic profile building, offering post-publication peer review can highlight your in-depth subject knowledge while engaging in community building.
