The are quite a few KINs out there but we know for sure where (at least) one of them is. Derek Snyder, Senior Product Manager with Microsoft and pocketnow.com alum uses his KIN(s) frequently to post on his Facebook page.

And we know that for sure because Facebook features special icons for services linked to Facebook and Derek’s latest updates are tagged as being made from KIN.

Even more, Twitter seems to already tag KIN tweets and since we only know about Derek, you can check the integration on his Twitter page.
