And if we're going to make so many mistakes (1/1000 means thousands of
mistakes), I'd rather it just be left as "Dr Martin Luther King Blvd".

Yes, we can't stop people from making mistakes.  But we can refuse to
allow thousands of mistakes to be added, for the sake of removing
abbreviations which aren't hurting anyone in the first place.

But its error rates are potentially much more annoying.  "Doctor
Martin Luther King Bolevard" is one thing.  "Drive Martin Luther King
Boulevard" is another.  The latter will be much more difficult to find
at a later date and flag for review.

Maybe you won't make that particular error, but you're going to have
to be really careful to avoid making any errors like it.  And relying
on the TIGER tags may or may not help.  I wouldn't be surprised if
many of the TIGER tags themselves are screwed up, based on the kinds
of mistakes I've seen in TIGER data.

Yes, I said if a bot is smart enough to go through the history tags,
then this *does* provide an advantage over data consumers doing it
themselves.

Re: [Talk-us] WTF happened to Bing's imagery of Mackinaw City, MI?

[James Mast]

Wow, this is messed up.  I just took a look @ Google's imagery and it isn't 
blacked out.  Looking at it, I didn't see any reason for it to be blacked 
out.. http://g.co/maps/yxrkg So, it must mean that somebody in Bing is 
doing this for fun possibly. --James ___

For some reason, the city is blacked out, but the black only extends to 
the shoreline.

I was able to download a .shp file from the viewer.  It had changes in it date 
in 2012, so I assume that it is current.
