History:
* First there was Andy's green/red Tiger fixup map.  That was a great
simple map. The map would go from red to green when you killed the reviewed
tag.
* Mapquest picked up this map for a bit but it died when the group was
decommissioned.
* Itoworld was a nice version that added many more colors and the date last
touched.  The map was damaged when certain tags were no longer saved with
each edit.  These were removed in the background.  I started removing all
the Tiger tags because most of the map started turning black.  You could
tell what was edited or not.  The map almost reverted to Andy's map.
*There was a Battle Grid map. The original was lost but there is a
replacement that you have to run by yourself as far as I can tell.

My problem with Battle Grid map was that the the colors were too light when
you revised Tiger data.  I liked the idea because it reminded me of the Who
Did It Map. Something simple like a grid but use two colors like the
original fixup map but with no fading.  All each tile at zoom 16 needs to
do is change color and tell you how many more ways need to be touched.
Most of the tiles would be red until you touched all the roads.  Then the
tile would go green.  Again my approach is to removed all the Tiger tags
because the street names have been expanded.  I don't do this on major
connecting highways because I am not sure that all the routes have been
defined yet.  Tiger will have some of that route data in the list of tags.

April 2050  for nodes
June 2028 for ways
based on Ben Discoe's burn rate calculations.

Ben's spreadsheet mentions all these mappers except for balrog-kun for the
western states name expansion bot.
woodpeck_fixbot
TIGERcnl
jumbanho
jremillard-massgis
bot-mode
DaveHansenTiger
balrog-kun

I often use this list of mappers as a way of checking Tiger progress.  Note
that woodpeck_fixbot removed Tiger tags on nodes.  Hence, you have an idea
if the street has been touched or not for most of the cases.

Finally, I am not sure that OSMOSE would be a way to track Tiger data.  I
like the positive idea for moving forward.  I suppose that a pin would
render on every Tiger way might work.  The cycle times on some areas a
really slow in OSMOSE.  You'd have to close all the pins after each edit to
see how you are doing.  That effort adds to the pain.  I think the
challenge for the U.S. project is that most of these maps have been
maintained outside the U.S.  If implemented, I am not sure how long OSMOSE
would provide the service.
