For me best feature of social media is the video call it enables family to bond even their far apart from each other. It helps everyone to conveniently connect with each other. I also like the reminder thingy about the events in your life that you posted. Right now I can't think of anything that they could add but I agree with megynacuna it would be better if they can add BTC option or button on the app that will help BTCers when sending and receiving payments. In case they do I hope they will ensure that it is really secured.
