Kin Spot is a little hot spot at the bottom of the screen almost akin the virtual "binding" in Courier. You can drag pictures, addresses, web pages, and other media into it, and then drag the faces of friends who you want to send the stack of stuff to. Once you tap the spot you can preview your message, add some text, and choose from MMS or email to send it out.

Kin Loop is the home screen, which shares much in common with the Windows Phone 7 home, except for its primary focus on people. You can see updates from news sites, people, and photo sites, and update your own Facebook, MySpace, and Twitter from a little widget up top.
It's a camera, but of course it's also social. You can upload to social sites right from the app, and it mixes between video and stills pretty freely. There's also a pinch-to-zoom gesture for cropping photos while you're taking them.
Perhaps the biggest surprise or outside-the-box feature is Kin Studio. Basically, it lets you do everything you can do on your phone, like share your photos, update your status, etc. (even using a Kin Spot UI to do it), but it also acts as cloud storage for all your media -- including a scrubbable timeline for checking out your own archives. You can also do contact management from here, another nice perk.
