This was interesting to read. I’m in the community support role at another crowdsourcing project (wikiHow.com) and this is one of the main things I help to mediate. Newcomers make the same mistakes and ask the same questions again and again; it can be hard for long-term contributors to not get burnt out by this because it feels repetitive, even though it’s a different person every time, and each person is often innocently asking a reasonable question, or making a common mistake. I’m curious to learn more about how OSM deals with this.
