visual comparison of online censorship

a visualization that allows users to quickly identify the most significant differences in content between 2 lists of Web pages, meant to help comparing the effects of censorship policies on search engines. one interface simply compares the image thumbnails of 2 identical search queries by putting them next to each other. the textual visualization shows the individual tag clouds of the 50 terms that are most particular to each query's results.

while the goal seems quite intriguing, the visualizations seem to require extensive visual comparisons. any ideas how the authors could make the interface more efficient?
