= products and services that make it downright simple (if not effortless) to contribute to anything, from pinpointing roads in need of repairs to finding signs of extraterrestrial life. 
- Test launched back in March 2011, the Boston based Street Bump app takes advantage of the sensors on smartphones to give city officials a real-time map of road conditions. The Android app uses the accelerometers and GPS technology in users' phones to register when and where the user's car has experienced a pothole, which it logs and reports automatically.
- Israeli crowd-sourced traffic navigation app Waze reached seven million users across 45 countries in October 2011. The app provides free turn-by-turn navigation alongside live information about road conditions, crowdsourced from other users. Users can also sign-in and view their friends' locations.
