Video tutorials - OpenStreetMap Wiki really would benefit from listing some
OSM for History Buffs - YouTube has a ton of content.
Do you have an idea what specifically can be linked on Wiki? And how it would be described?
Using the OpenStreetMap website - YouTube and First Steps in OpenStreetMap iD Editor - YouTube seem very relevant, as well as Downloading hiking trail gpx from OpenStreetMap - YouTube.
There’s also A turbo introduction to Overpass - MInh Nguyễn - YouTube.
I think these video titles are self-explanatory.
I edited Video tutorials - OpenStreetMap Wiki a bit based on them.
