osm seems like a mess. your comment got me poking around my local area to see if they had marked a recent road closure i was aware of. They hadn't, and the Walgreen's next to the road was marked as a generic building. I dug into the editing tools, made an account, and made some edits. Then I tried asking OSM to give me directions to that pharmacy, and it just says it can't find a route. lollll great thanks OSM.
It seems interesting as a hobby to keep up with. Feels like editing Wikipedia articles but you're getting in on the ground floor, so your individual contribution is way more valuable.
