The site looks gorgeous, fair play. I've seen from the comments that you're looking for people's envisaged use cases, so here's mine - I have moved about a lot, I'm currently living abroad. In a few months time, everyone will start moving about again.

This seems like a brilliant way to keep up with friends that I can't see very often, in a way that seems more genuine than the loop of "Hey we haven't talked in ages! How are you doing?" "It's been so long! I'm good, and you?" "Good :)". Being able to see what they're thinking and to interact with them from that without having to prompt a deep conversation on a Tuesday afternoon sounds wonderful.

Looking forward to using it more, and seeing where you take it!
