Filtering, curation, aggregation and relevance have long been touted as the next important steps for social media. In actual fact we've had curation services in the form of Digg, Reddit, StumbleUpon, Delicious and many more for a long time. However, the questions "How do I find the blog post, tweet, facebook update, photo or check-in that is most relevant to me?" and "How do I know I've not missed a really important piece of news?" are still asked daily. So, there still isn't a definite answer - or a definitive service. Cadmus started off as a "real-time filtering service" for a product called ViewPoint, but has grown into a self-standing application and the Cadmus API can help users and developers answer these questions.
Singly has announced the open beta of its app connection platform. The platform consists of two main components (i.e. the App Fabric SDK and the Data Fabric infrastructure). The App Fabric simplifies social data sharing and shortens time to enable functionality such as friend finding and login across multiple apps. The Data Fabric allows developers to integrate features like synching, data querying, intelligent indexing, instant push, archiving, and more.
Microsoft has announced its new Facebook SDK, which allows developers using Microsoft technologies to quickly create web client (via Silverlight), web server (via ASP.NET) and desktop (via WinForms and WPF) applications that harness the power of the Facebook API.
