This is the sort of thing I do in my local area; update OSM with anything I notice that's missing and seems like it belongs. The bulk of my updates are local trails through the bush from when I go exploring, based on my GPS tracks. But I've also been adding pedestrian paths between streets, new roads from residential developments, and so on. I'm guessing it just takes a few of this kind of person to keep OSM up-to-date. It's a shame it's not more widely used directly by the general public with some way of flagging errors.
