This document outlines a research agenda for Web 3.0 technologies focusing on location awareness, ubiquitous collaboration, and their impacts. Key questions are proposed around how location-aware information delivery and contextualization in space affects memorability and knowledge organization, and how optimal collaboration structures can be measured and supported online to enhance learning, content production, and social outcomes. Relevant learning and social theories are discussed. Usability factors like task-fit and multimodal information are also addressed.
