This document describes Drop, a new social platform that aims to help users better organize their digital lives into topic-based groups similar to real-life social circles. Drop allows users to create private groups on any topic, with access granted only by solving challenges set by the group admin. Within groups, users can browse and vote on various content types from websites to videos, and even host group content on their own servers. The goal is to bring like-minded people together through these guarded private groups while giving users control over their online social experience and reputation within each group.
