You can select individual streets and edit what classification of street it is
you can put in mailboxes,ATMs,restaurants and parks and edit specific information such as if the ATM has a fee or what the carrier the ATM is
the data for the U.S map comes from U.S government tiger
You can view the map in cycle view
other similar toposm.com topographic version of open street map.org

third party apps are availble for mobile phones that support osm such as NavDroid
Open Street Map is available in multiple languages in cities with high minority concentration in certain areas
you can use walking papers .org you print out maps to write on while mapping out a city then scan them back in to use on osm
you can also use gps to trace hiking trails that are beneath the trees
add lakes that aren't in the map by finding them on satellite view and tracing them in osm
