This unofficial Java library is for Android developers interested in working with App.net. Although the library is still being developed, it currently supports most of App.net's APIs like: post and user endpoints, message and channel endpoints, file creation and retrieval endpoints, and place search. The library is also set up to be used with Android Studio.
Moxie Software has released Engage+,"the first social chat app that leverages Facebook’s social graph leveraging public profiles to target social visitors with unique proactive offers and provide agents with a rich set of social data." Until now, sales and customer service reps had access to limited customer data when interacting with customers via chat (e.g. customer name, purchase history, email, perhaps a few other data points). Engage+ utilizes Facebook's social graph to further understand and engage customers during chat conversations (e.g. age, brand likes, friends, mobile usage, and many more data points). Deeper profiling during a customer interaction allows companies to produce customized offers pinpointed at specific customers.
Forrst is a community for developers and designers to connect and collaborate. On Forrst users can share links, code, and in-progress projects, as well as discuss these things. This sort of community is always useful, as many eyes on projects can lead to spotting errors faster and making things more efficient for everyone involved. However, a simple website isn't all that's needed for true community-building these days. Developers and designers are the sort of people that use mobile devices extensively, and also the sort who love mashups and the like to save time and effort. For those people, Forrst has recently released the Forrst API, allowing access to Forrst through RESTful calls. And since that's the sort of feature developers want to see, they've been clamoring for Forrst's API, despite the site itself still in closed beta.
