Abstract:
1. A machine-implemented method for visualizing changes to content over time, the machine-implemented method comprising: obtaining content from a content source; saving a state of the obtained content from only one item of a group of items in one of a plurality of resolutions, a first one of the plurality of resolutions including first information for exactly reproducing the content, and a second one of the plurality of resolutions including second information for re-querying the content source; comparing the state of the content with a previous state of the content from the only one item of the group of items to determine difference data that reflects a difference between the state of the content and the previous state of the content and to produce difference that is displayable together with the content, via an electronic display, as visual indicators within the content; displaying, based on the difference data, one or more changed portions of the obtained content and one or more unchanged portions of the obtained content; degrading the saved state of the obtained content to a lower resolution by deleting information in the content after an age of the saved state of the obtained content exceeds a predetermined amount of time; and degrading the displayed one or more changed portions of the obtained content and the one or more unchanged portions of the obtained content, when the resolution is degraded.
