Yesterday I created a filter in OSMCha to get all edits made by new users in Brazil, as we are having a new wave of Pokemon motivated edits. Today I spent some time reviewing some of those edits. I sorted the changesets by the number of features created and started by the big ones.
I reviewed 11 edits, six of them had between 132 and 400 elements created, and 5 with 400 to 510. It was a surprise to me that only ONE of those edits was bad (the user created a river that doesn’t exist). Some edits had some small errors of course, but nothing very dangerous to the map quality.
So, believe in new users, they also can do amazing things and congratulate them by their good edits!
