There are already millions of apps available that have great content, and there'll be many more to come. GROUPcentric provides a product that aims to add a new and exciting layer in social sharing functionality that allows content to be shared, not only via the large scale Facebook and Twitter options or email and SMS, but an in-application sharing service that makes it possible for users to privately share content with groups of friends that can be accessed on any app. The GROUPcentric API and SDK allow developers to integrate this functionality 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.
