Photocase recognizes photos and users that are of special interest and stores this information. We measure the interest using a crack team of analysts who constantly monitor a highly scientific system of algorithms and…ok not really. Actually it’s relatively straightforward although there is a reasonably complex procedure to determine "interest" that involves comments, votes, downloads, links and last but not least, how recently it was posted. The list is changed by user interaction, so the more you visit, the more it changes. You might be pleasantly surprised.
