Those aren't the real challenge. The real challenge is annotation software has an anti-network effect: https://news.ycombinator.com/item?id=23576213 https://news.ycombinator.com/item?id=23576213 An AI system that tries to summarize the annotations to tame the chaos might be interesting, though whether people are willing to "engage" with a system that takes their input and merely feeds it into an averaging model such that nobody will ever see their actual comment might be a tough sell.
