A platform allows experts, for example home improvement professionals, to upload their portfolios, i.e. content such as photos, videos, text, and sound, to a publicly available resource, such as a Web browser accessible, network based commerce system. Users may then browse the content, for example by room, style, and metro area. The content is arranged in collections that are in part passively sorted, based upon user relevance. Tags are shown on objects, for example within photos, for which there is more information. In the case of a movable display device, the tags can simulate the physics of real tags, for example they can move back and forth when the device is shaken. In another embodiment, a snap point is set to impart either a scrolling transition or a step transition between display pages, based upon user scroll activity.
