A number of qualitative and quantitative tests were performed to evaluate the performance of the Hovercards feature. These tests were focused on the following questions:
 * Do users enjoy Hovercards and find them useful?
 * How do Hovercards change reading behavior and do they help users be more accurate when selecting the articles they wish to read?
 * Would launching the Hovercards feature have effects on fundraising?
