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.
We update it a lot. We also have a product (for walkers in the British Isles) called WayMaps (used by a variety of walking web sites in the UK and also our own demo site https://waymaps.the-hug.net/) which uses the geodata from OSM and other Open Data to produce our own map tiles. We love OSM.
