Hey, I loved the idea of NanaGram: not only sounds good, but also it is a startup that makes the wolrd a better place.
However, after a few minutes checking your website, I noticed that all the old people I know (my partner grandmother, my friends' grandparents, etc), they all use Facebook or Whatsapp in one way or another, so it is really easy to send them digital photos. And considering I am from 3rd world country, I wonder how that is not the case in the United States.
