Our users can log their ski trip, hiking trip or sightseeing trip, upload it to Breadcrumbs with their photos and videos, and send it to all their friends, who can relive the adventure in 3D. And this is only the start, as we plan to provide our users with a platform to not only edit and maintain tracks, but also to find new places to explore and interact within a social network.

Breadcrumbs is the first web application of its kind, where users can manage GPS tracks, photos and videos in one place - it can be thought of as 'Flickr for GPS tracks'.

The key features of Breadcrumbs include:Relive your adventure: Breadcrumbs brings together photos, videos and GPS tracks in one quick and easy process and our 3D playback function brings the track alive. Edit and manage: Breadcrumbs comes with a suite of tools which let users edit and manage their GPS tracks, photos and videos. These include:- Automated geotagging of photos.- Track editing tool to correct GPS points.- Add information to your adventure to help tell the story, such as show where you ate your lunch or spotted some wildlife.- Organize: Breadcrumbs offers a rich set of tools to help users to manage adventures.- Share: Breadcrumbs makes it easy to share adventures, with options including a public page for each track and direct integration with Facebook.

They matter not at all. The mob, now mobilized, will do as it pleases. Obama can lead by example, can encourage or scold as occasion warrants, but he can not control. Not with all the King’s horses and all the King’s men.

Only a decade ago the network was all hardware and raw potential, but we are learning fast, and this learning is pervasive. Behaviors, once slowly copied from generation to generation, then, still slowly, from location to location, now ‘hyperdistribute’ themselves via the Human Network. We all learn from each other with every text we send, and each new insight becomes part of the new software of a new civilization.

We may have had great hardware, but it took a long, long time for humans to develop software which made full use of it.

While used textbooks are obviously less costly, they often carry another benefit new textbooks don't: highlights, underscores and other annotations by their previous owners. Even though the author of, and rationale for, the annotations may be unknown, the fact that somebody found particular sections of the book important enough to emphasize tends to make the eye linger. Ideally, annotations can make learning and knowledge discovery feel less like a solitary pursuit and more like a collaborative effort.

At first glance, it would seem that the trustworthiness of an unknown individual who has interpreted or appended an author's work would be questionable, but several reasonable assumptions can be made that contribute to the perceived authority of an unknown annotator. At the very least, they read the work and took the time to make the annotations, which may question or clarify certain statements in the text, and create links to other works, authors or ideas. The subsequent reader of an annotated work then has one or more additional perspectives from which to evaluate the usefulness of the text and annotations, and more implied permission to add his or her own interpretations than in an unannotated text. Published scholarly works are objects for discussion in an ongoing conversation among a community of knowledge seekers, and whether via formal citation in later publications or annotations in existing ones, all are designed to advance the generation and exchange of ideas.

Most critically, knowledge discovery and transfer is no longer restricted to a model of one expert creator to many consumers. In Web 2.0, consumers are creators, who can add their voices to both expert and non-expert claims. Users get the benefit of multiple perspectives and can evaluate claims in the best tradition of participative, critical inquiry.
