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.
I don’t think the aim is necessarily to compete against commercial alternatives but rather to have a backstop/fallback if/when they fail.
Also don’t forget LOTS of commercial providers use OSM data for their mapping. So eventually a lot of the data does make it into people’s hands.
