How did I get involved with OSM? Initially I was looking for open data to use with flight simulators. I found that my local area was mostly blank so I started adding bits. You can guess the rest.
Since then it's been very handing for keeping my aging Garmins up to date as well :).
I am proud of the fact that my local area shows a high level of detail, compared to neighboring areas, and completeness. See ITOworld for example.
