As a user, the concept of "nearby" isn't as clear as "maps". I know exactly what a map is but I don't quite know what to expect when I see a feature called "nearby". Similarly, if someone said I should try the new "Wikipedia Maps" feature they read about on Hacker News, I would think it would have something to do with mapping. Maybe even kind of like Google Maps or Apple Maps. The "Wikipedia Nearby" feature sounds more like a social network and I'm not sure what the implications are without having to check it out.
