when assessing TIGER, it's good to keep in mind that it's a moving
target. the
copy that was imported into OSM was the 2007 version, which was midway
the improvement project, and the reason why some parts of TIGER are much
bad than other parts of TIGER in OSM.

there are various layers available which render newer TIGER so it can be
used as
a backdrop image for editing, i sometimes use these when cleaning up older,
obviously bad TIGER.  and TIGER really is improving. a major part of
that is that
the Census Bureau is trying to work with local GIS departments more and
their direct involvement in maintainence, which seems to me to be the
right way
to go.
