CloudMade help you make the most of map data. We source our maps from OpenStreetMap, the community mapping project which is making a free map of the world. Our aims are to continue the democratization of geo data and to expand access to open geo data through a range of simple yet powerful tools and APIs.

Our first set of APIs allow developers to integrate high quality maps into mobile and web-based applications.

Yikes! Message up to 1000 people at a time? Sounds like spamming.

Twitterfall is a way of viewing the latest 'tweets' of upcoming trends on the micro-blogging site Twitter. Updates fall from the top of the page in near-realtime.

Unlike other sites, Twitterfall purely does trends (for now). Because of this, we can be efficient – Twitter is queried from the Twitterfall server, and results are pushed to your browser, rather than your browser doing the queries, or your computer polling our server repeatedly.
