But yeah, not sure how scalable even such a campaign would be. I’m the only user I know that use EveryDoor to confirm/update POI in a city of 500k people…
You’d probably need at least 1 out of 1000 people globally to actively contribute. That’s almost 10 million people, quite a bit more than the 1 million Organic Maps users and 250k OSM contributors in 2022 :)
if anyone here is interested and unsure how to start, feel free to ask at https://community.openstreetmap.org/ (official forum, requires OSM account) or at one of other contact channels ( https://wiki.openstreetmap.org/wiki/Contact_channels ) - there is Slack, IRC, Discord and so on.
https://wiki.openstreetmap.org/ may help but it is sadly suboptimal for someone completely new.
If you just click edit you will get tutorial for default in-browser editor.
The way I started contributing to OSM is when I was tired of seeing old or no POI data and thought "enough is enough". I first started editing the shopping mall in my neighbourhood, then the schools, and so forth. It is now 5 years later and I can quite keep up locally with POI.
