We'll said. OWNERSHIP of your home turf would be a good subject for you to present at the SOTM 2018. It would appeal to those of us "unpaid mappers" who attend SOTM. All the 2017 sessions were interesting, but few related directly to how I map.
As Simon said, I believe there may be some validity to Abhishek Nagaraj's
findings on ownership. It's why so many people watch edits in their area.
They are quick to challenge poor edits in their watch area. I believe they
have a sense of ownership in the area. It's an attribute that would be nice
to encourage. I think of it more in terms of stewardship rather than
ownership, but either way, OSM benefits.
