Have you heard of StreetComplete? It's an Android app that shows you open questions/issues with OpenStreetMap in your area, and asks you to answer them.
It's made for people with no experience with #OpenStreetMap, so it shows only very simple questions that can be answered very clearly. ("What is printed on this street sign?", "What's the number on this house?")
