This document discusses a new social media app called ThoughtBubble that allows users to anonymously share short thoughts or "bubbles" in a specific location that remain visible for a set period of time. Other users can then upvote or downvote the bubbles. The app aims to connect strangers without talking by letting them discover what others are thinking anonymously yet with relevance to location. It competes with apps like Yik Yak and Whisper that also offer some level of anonymous sharing.
