A good presentation deck by Qianxing Lu and Brian Moritz for their Social Media Theory and Practice assignment.
In 30 slides there is a well laid-out synthesis of why a growing set of new curation start-ups have decided to focus on developing their own curation-filtering tool.
Simple, clear and well presented concepts.
Good synthesis. 8/10
