I looked back at the talk archives.  There's no context for this
discussion.  The moment I see something that says it is because of bad
imports, I start thinking that the issue and the supporting data is tainted.

Yahoo as a bad import?  How about a new mapper doing the best that they can
to improve the map added a few tags that a more experienced mapper can
build on?

Where I see someone like Norm Abram[1] make these wonderful jigs and
patterns as labor saving devices for wood working, based on the limited
context, you are saying that the same labor saving Josm Lakewaker plugin to
help a mapper trace a lake is an import or a bad import?

Ditto.

The importers that provided me all the NHD data are my heroes.  Those
imports gave me a great deal of material to work with.

In my case, you'll have to provide more context here.  I look at OSM
Inspector and Keep Right and see all these broken things.  That is a
beautiful discovery.  Mappers are trying to improve the map that is very
much a human endeavor and mistake prone.  I am just lost how everything is
a bad import.

Please Advise,
