The New York Times made news earlier this year through its release of several APIs (our Campaign Finance API Profile and our Movie Reviews API Profile). There's been promise of more APIs to come, and the latest prototype created by The New York Times gives a preview of what is to come.
Twitter co-founder Biz Stone has just announced a new geolocation API that will be available to developers fairly soon (Twitter API profile). The new API, which will likely be rolled out in Twitter clients before being available on the Twitter site, will allow users and developers to add latitude and longitude to tweets, thereby adding a valuable new layer of meta information to tweets.
For several years millions have shared the places they've been using the Where I've Been website and Facebook application. The site also has an API (our Where I've Been API profile), which allows for much of the same functionality, such as searching countries, marking it visited and adding content such as a story or photo.
