When travelling, the first thing on the list of things to do after arriving at a destination is to get in touch with certain people to let them know you're in town or just that you've arrived safely. Whether it's sending a quick text, sending an email or 'checking in' on a social network, technology has made this easy enough to achieve while on the go. Oh Hey World is a service that makes use of all these options in the form of a simple application that allows users to share their location across multiple social networks, via text and email, with just one click. Oh Hey World's API makes this functionality available to developers who may want to integrate it with other applications.
Location-sharing service Gowalla is preparing to launch its long-awaited write API (our Gowalla API profile). The move could makes its platform as desirable as its main competitor, FourSquare. With it, comes the need to relinquish a bit of control of the user experience, something Gowalla has considered an important factor of its success.
