Thanks for typing out the answer again.

Particularly regarding my question about “replacing Google Maps”, this was an illuminating answer. I’ve come from GMaps, and it kind of formed my notion of what a map program or site should be. I’ve never used the review system very much, preferring to make use of the public transport functionalities. This is, as far as I’m aware, not in the scope of OSM, so I found myself missing this feature, through no fault of the project at all.

Again, thanks for the answer. It really helps to recontextualize how I should think about OSM and the open source projects surrounding it.
