This document provides a summary of an idea for a website called PostEro.com that allows users to create and upload various types of content such as video, audio, text, and images to save and pass down to future generations. Users would organize their content on a timeline that provides historical and social context. All users would have a personal page to edit and manage their uploaded content. The site would also allow content creation directly on the platform and have an app to compile the content into an instant book that can be printed.
