I feel like they could do a little more in terms of promoting on their own website to add/update things. I use it, but so far never saw any "Something new here? Do xyz to add it to the map!". So I have no clue how to even start adding anything. Alternatively perhaps they could allow users to add things to some staging ground, where authorized users could decide, whether to take it or not. But I guess that would result in lots of spam.
