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.
OSM is an awesome project I agree it is fun contributing to it but it is not as useful yet due to what you describe, details.
Finding addresses and other specific information is very hit or miss in some areas. Especially in the US where no one really cares about it other than tech corporations using it for quick info like street layouts.
My entire city has address numbers missing and for a long time I used an app on my phone (StreetComplete) to fix address numbers and other various details. But it can be overwhelming very quickly depending on how outdated or not updated your place is. Time you enjoyed wasting is not wasted time by the way.
Try Everydoor as well. Another StreetComplete like App that’s great for adding simple items
