We want to analyze the user's connections and emails to figure this out. We do understand that there would be a lot of privacy concerns in this regard, and hence won't like to save any such private data on our servers. Once we derive this information, we present it to the user to confirm & save. If a user A adds user B (who already uses 128HS), then we need not worry too much about learning about B as B is already a 128HS user. The problem is with those family members who don't use 128HS. We also encourage the users to share interesting plans/places/events with their contacts (which the user thinks their contacts might like), we keep learning more about their contacts. We do realize that the same user behaves differently / has different preferences when on a grad trip vs a family trip. We want to generate the network graph accordingly. On another thought, we were also looking at gamifying the entire trip planning exercise among family members with incentives for inviting family members to plan trips collaboratively - just an idea, didn't think through too much in this direction.
