One of the most powerful aspects of mashups is taking similar data from competing websites and providing a single place to examine the content. In this round-up of the best new mashups we'll look at three apps that aggregate data from multiple services. One looks at location check-ins, another at shared photos and another mashes photos with information about where they were taken.
