Welcome! I am also on OSM (under username us89) but don't really do much editing. The idea is cool, but it seems like doing anything substantial is a lot of work, and I'm not a fan of the culture over there. A lot of people seem to have really restrictive opinions on how things should be done (i.e. what should be trunk, motorway, primary etc.) and act like there is no room for any sort of disagreement.
There is one particular user over there who is particularly egregious for this and I think is the reason why NE2 isn't on OSM anymore. He used to be on this forum too, but got banned from here for something unrelated.
