Show HN: Which Airbnb did your friends stay in?

Wouldn't finding where your friends stayed increase your confidence in selecting an Airbnb?

Facebook took the network graph SDK away and all social features in apps just died between 2016-2018.

However, those network connections still exist on our phonebooks. I thus built the ContactsManager SDK - to build a network graph, while ensuring privacy of users and their contacts. I don't think anyone wants another Cambridge Analytica scandal.

Thanks for your comment, not sure what you're trying to imply, but don't you think DoorDash or Airbnb would be significantly more valuable if it told you what restaurants/Airbnbs your friends like as well? As compared to reviews from strangers.

[I see the irony as I ask strangers for reviews lol]
