In a nutshell
Plaudit allows researchers to publicly endorse academic research, and makes this data openly available. This provides a clear, simple and accessible signal about the quality of an academic work, that builds on the knowledge of your academic peers rather than the reputation of the journal it is published in.
Goals and intentions
Plaudit was created to improve the incentive structure in academia, in which researchers feel pressured to publish their work in "top-tier", but often paywalled journals, or journals with a substantial publishing fee. By providing an alternative signal of quality that still relies on the expertise of your academic peers, the hope is that that pressure can be relieved.
