Reading/Readers contributions

About
After the work on community of readers and the user interaction consultation, the Reading team would like to move forward with a conversation that helps the team frame a theme of products, where readers are actively contributing to alleviating some of the required editing tasks, i.e: What kind of tasks that could be done by readers or casual contributors, and which are needed (and welcomed) by editors, at the same time?

This work is initiated by the Android team. Selected ideas will be implemented on Android, as an initial stage before the move to web, as well (if community and team decided to move it to the web).

You can check the Reading team thoughts on the topic here, while below is a list of suggested tasks, and their evaluation based on some criteria. Please feel free to add more ideas, and add to criteria if needed.
