Add Applause-button to swag items

It would be a simple and nice feature wherein a small applause button accompanies a swag item. Users can '+1' it if they feel this is a nice opportunity, and sorting can then also be done on the basis of the number of applauses an item has got.

Implementation of this is fairly simple: https://applause-button.com/. This allows for Medium-style applause buttons on static websites with a zero-configuration setup.
