Preach it brother!

I think we've learned two things from the last few years of imports:

1) Imports are hard to do right

2) Imports with existing data on the same area are nearly impossible

3) It only takes a few minutes to import, and years (or longer) to
clean up a bad import

4) Imports' impact on the community is controversial.

I know I've talked with you personally about this problem and we've
floated a few idea, but here are some thoughts:

* Bing Imagry has been Good

Imports are bad, but imagry is good.

I think that's because people feel they're a part of the process when
they trace or correct tracing through imagery. We should try to create
a process that involves people as much as machines.

* We have a map of reviewed vs unreviewed TIGER data. We should use it.

* Other examples of import comparison tools exist

Let's try to look at other tools like Musical Chairs or the Canadian
Import tool and if not use them directly, see what we can learn.

* We have our own dataset from GPX data

We often forget we have our own datasets in the form of GPX traces.
Let's not forget that.

There's nothing direct or practical here.

What do people think of a phone or IRC meeting, getting everyone on at
the same time?
