This SDK helps developers integrate Facebook into their web, desktop, and phone applications using ASP.Net or ASP.NET MVC. It can be used to create social Windows Store apps that run on Windows 8, or to allow Windows Phone users to authenticate via Facebook and post status messages through their apps.
Nothing on a social website gets old faster than looking at the default avatar. That's the square graphic meant to represent a user who hasn't uploaded a photo. There's nothing to be done about this, right? Think again: there's an API that can give all your users a unique graphic.
The Swipp API allows developers to integrate Swipp's "Social Intelligence" into their sites and applications. Public information is not available on the API; interested parties are asked to email firstname.lastname@example.org. Once available the APIs will "make it possible for people to interact around any topic imaginable."
