Hi. When I said "let's not make [spatial data] special" what I was implying
was that there needs to be a low barrier to usage. So if someone is trying
to do something simple, then it should be easy to do. Of course, that means
that we experts need to make sure that the best practices we provide steer
non-experts well away from pitfalls for those simple activities.
