OSM is a really cool idea, and a fantastic dataset! For people curious about what it's like to use OSM in a huge company, a couple engineers from facebook were recently on a podcast discussing it: https://softwareengineeringdaily.com/2020/04/17/facebook-ope...
Some interesting tidbits: FB are hyper-conscious of "graffiti-edits" that can sometimes sneak into OSM, so they built a system to self-host the OSM data, which periodically and selectively merges chunks of data from upstream, using fancy algorithms to flag "suspicious" edits upstream.
