When I was asked about inviting people to Path as I installed the app I said no, and without entering much in the way of personal information Path decided to text my entire phone book for me the day AFTER I uninstalled it from my Android.
Maybe that’s the real reason Path CEO Dave Morin doesn’t have a ringtone.
Update: Path told The Verge that it’s a feature:
By default, Path assumes you want to send a message to all your Facebook friends, displaying a list with every name checked. The user must then tap “unselect all,” or Path will text a signup link to every friend. This configuration has been in place since Path’s last release on March 6th.
