I've tried using it over the years but I never liked it because there was no information. So last night I looked at my local city and there is almost no information at all. I spent a few hours last night adding buildings and restaurants and removing incorrect items. It was actually kind of fun and therapeutic and I plan to do more of it tonight. My girlfriend thinks it's dumb and I'm wasting my time because Google maps and Apple maps and Bing maps exists but she just doesn't understand open source.
Edit: Apologies, I just realized this question is not Linux specific.
Yes I use OSM almost exclusively and have contributed to it.
Where I live, in Germany, OSM is pretty much on the same level as Google Maps and way better than Apple Maps. Sometimes there is outdated info but you can quickly correct it. Sometimes I double check stuff with GM.
Some information is even better than GM. But I think Germany has a pretty strong OSM community, at least in my city.
Same here. I downloaded it recently to have a look and just realized how easy it is to update information for places that I frequently visit. What I like about that is that I can add information isn‘t listed in any map, because shop owners other people responsible don‘t bother (yes, people like this exist).
Make an account on OSM, find something wrong on the map, update it.
Start with your commute or places you go. Check the information, I often find wrong opening hours. Maybe some constitution altered something. You’ll find something.
