Yes, I’ve populated most of my local area, and every time I go for a walk or bike ride, I add as much detail that I can. I also find it very enjoyable and it’s pretty cool to see features I added show up in all kinds of mapping services that use its data
Osm now has the clearest and most detailed maps for walking that I know, and I use them in preference to the UK’s ordnance survey maps, which don’t scale so well on electronic devices.
