OSM is a truly incredible resource. It's often lightyears ahead of proprietary maps in terms of feature accuracy. Often far behind in terms of points-of-interest.

It powers painless adding of maps to so many products, painless offline data analytics and joins (I built https://wildpocket.com/ by joining OSM to iNaturalist data).

Truly incredible and under appreciated by general public. I love street complete, it opens up OSM to so many beginners with the simple UX. I think there's an ongoing need for "beginner-friendly" OSM tools - I've prototyped https://mapmender.com/ to help map the "last mile" routes for emergency response that are inherently hard to keep updated. It's a WIP passion project, feedback welcome
