Nice post and always exciting to get a good start going. What I'm really interested in is the geographical dispersion of those 1,000 users (and however many you have now), how many conversations where actually formed, and the retention.
I guess people fire up an app just after installing it, wanting to take it for a spin, and if they can't form even one conversation since nobody's around them, it would greatly affect retention.<p>An interesting metric would be 'conversations per day' and if technically possible 'potential conversations per day', that is to say how many pairs of people with the app running where in 1 mile proximity to one another.<p>Also, it would be interesting to see whether users take the conversation elsewhere (facebook, twitter, whatsapp), at what stage (as one is leaving the location or before that), and if they do - how does it affect their app usage. Does it make them use the app more (for example, to seek more connections and friends now that they see it's effective for meeting new people), or less (they took the conversation elsewhere and their social needs were met for now).<p>Just my $0.02. Hope to see an Android version soon to test if myself!
Good luck!
