What I mean about "spread"... You can use facebook comments, genius annotations or even ask for comments in leaderboards platforms like reddit or HN.

Thinking about delegated systems I can only see two purposes: a) Make your project/content be acknowledged by the people (Spread by piggybacking) or b) Cut off engineering resources regarding to the lack of value created through those comments.

At some point, we need to decide if the comments are a value to keep or to trade.
