The original idea was to build a web service designed to serve isochrone and isodistance polygons. The final purpose of the application, which is an implementation of the web service, is to display bakeries locations within isochrone (or isodistance) polygons, centered around a user-defined point. Users can then get the shortest path to one of the bakeries.

For a long time, that’s been a tough question to answer. In dense, bustling cities like Chicago, New York and San Francisco, the number of daily media reports, government proceedings and local Internet conversations is staggering. Every day, a wealth of local information is created — officials inspect restaurants, journalists cover fires and Web users post photographs — but who has time to sort through all of that?

Our mission at EveryBlock is to solve that problem. We aim to collect all of the news and civic goings-on that have happened recently in your city, and make it simple for you to keep track of news in particular areas. We’re a geographic filter — a “news feed” for your neighborhood, or, yes, even your block.

Brightkite connects people based on the places they visit in the real world. With Brightkite you can see where your friends are, what they’re up to, see what’s going on around you, and meet real-world friends.

Most people who have tried the service understand that Brightkite doesn’t really track you, it’s up to you to decide how often you “check in”, and at what accuracy. On top of that, we have pretty comprehensive privacy controls.

SKOUT enables users of virtually any mobile device currently available to create content—messages, photos, videos—with their handsets and post it to the SKOUT network from any location.
