Rosenberg is currently pondering the creation of something similar for “report an error” functionality. There are currently some large news Web sites that offer this—including the Toronto Star and Huffington Post (though theirs is hidden near the bottom of articles)—but it is by no means a standard. The New York Times, The Washington Post, the Los Angeles Times, and CNN, among many others, don’t include that option on their articles and pages. It’s such a simple, effective way to collect error reports, not to mention give readers a chance to participate and contribute.
But where it should be placed on the page? Do we need a universal icon? How about the interface that pops up after you click on that button? Should that be standardized? The fundamental idea is sound, but there are lots of details to work out. Rosenberg is thinking of the best way to move forward with the idea, and I’m hoping to help.
We’d also like you to share your advice and input. Consider this an invitation to chime in with your choice of the call-to-action language, the functionality, the placement, etc. Are you a designer who’d like to try and create an icon? A site editor who wants to join up and get the result on your site? Add your comments below and Rosenberg and I will join in and follow up.
Oh, and as for that Journal correction request? They fixed the article but never added a correction. So we also have much work to do in terms of standardizing corrections. But one campaign at a time.
Correction of the Week
“An article about edible flowers in Wednesday’s Taste section included some examples of flowers that are not edible. These flowers, mentioned in the story, should not be eaten: lily of the valley, iris, hyacinth and some species of jasmine (Jasminum sambac flowers are edible). Linden flower tea can cause heart damage with frequent consumption. The Sun regrets the error.” - Baltimore Sun
This is rich: Perhaps two weeks ago I posted a correction here, at the CJR, on an article "How Big Is Big? When numbers are meaningless" [By Merrill Perlman] about how numbers in news articles don't mean much unless interpreted in terms that readers know. The error was that a square mile is "about" 640 acres, when, in fact, it is exactly 640 acres.
Then, I went on in my comment to make an error of my own. (Serves me right, I suppose). I was quite wrong about the size of a US football field. This was helpfully corrected by another reader.
However, the original error stands in the article, underscoring by example the need for an effective error-correcting mechanism.

Didn't see your initial comment, Nicholas. Sorry. Will correct Merrill's article now. If this sort of thing happens again, try e-mailing editors@cjr.org. We're usually pretty responsive.

Lesson learned for me: Don't trust Apple's Calculator for area conversion. It says 1 square mile is 639.999998790047318 acres. When converting the other way, it says 640 acres is 1.00000000118506 square miles. I don't know if that's true of all versions of Calculator. Mine is 4.5.2 (97), the version included with Snow Leopard.
I also did a quick sampling of online conversion utilities. Of the first 10 Google results for "area conversion," three of the online utilities got the answer wrong (including the top-ranked conversion utility) when converting from square miles to acres or from acres to square miles or both.
Thanks for bringing this up, Nicholas.

I recommend a funky but extremely useful application called Frink (found at http://futureboy.us ) whose author, Alan Eliasen, recognized the lack of physical units in programming languages and wrote Frink to redress this. Frink has many, many systems of units, not just physical sizes, weights, etc but also relative values of currencies, varying values for some over time (with automatic lookup of tables of such info on the web) and much more. It's a free Java app, thus cross-platform.
Alas, even Frink gives the wrong answer for: 1 mile^2 -> acres
249999000001/390625000 (exactly 639.99744000256) , and I have no idea what the fraction it bases its wrong conclusion on represents. [I haven't brought this to the attention of the author, yet.]
This shows that conversions must be tempered with a bit of common sense. When a result is very nearly a round number, it is worth taking another route to see if your first result is not simply a round-off error.

Actually, Frink is exactly right, and the original statement that a square mile is "about" 640 acres is correct. Nicholas wrote to me and told me that Frink was wrong. Here's my response to him, which hopefully sheds some light on the issue of these historical units of measure.
Actually, Frink is exactly right, and it's important to know why it's right.
Other converters get this wrong due to sloppy research.
The short answer is that the furlong (and league,
acre, rod, statute mile, township, chain, etc.) are all defined in terms
of the *survey* foot. This is the definition of the foot used in the
U.S. up until July 1, 1959, when its value was slightly changed (by 2
parts in a million, as you can see) to the current value of the
"international" foot as exactly 0.3048 meters. Previously, it was
exactly 1200/3937 meters, which can't be represented as a finite decimal
number.
Surveyors still use the old definitions, and the correct definition (by International standards body and by law) of the acre and other units need to be based on the old "survey foot" definition.
Any time Frink gives you a result that is a multiple of the fraction
499999/500000 when working with lengths, you'll know the old survey foot was involved.
If you use, in Frink:
1 statutemile^2 -> acres
then you'll get the result you want. The "statute mile" is the *old*
mile using the outdated pre-1959 definition. The modern mile is just
called the "mile" or sometimes the "international mile" if someone's
making sure which mile is to be understood. Frink also uses the term
"surveyfoot" if you want to use the old, outdated definition of the
foot, say, when converting acres to square feet.
Surveyors still use the old definition, and if you want to be
correct, (and I do,) you need to use the right base definitions for all
the derived definitions. This is a common question, and people are
often suprised to hear the history (unless they work in a geographic
field, and then they run into it 50 times a day.) Ask a surveyor about
the fun this creates. Every one of them will have some stories.
Also see:
http://www.sizes.com/units/foot.htm
or NIST Special Publication 811.
http://physics.nist.gov/Pubs/SP811/contents.html
(This uses underlining to show the units that were defined in terms
of the survey foot. Be warned that later versions have typos and
mistakes due to a change in the software they used to produce it. I
reported these to them and they've acknowledged them as errors to be
fixed. I haven't checked those publications in the last couple of years
to see if the changes made it in.)
I really do scrupulously research these things (I've probably
researched every major measure in Frink's data file at least 5 times,
usually against the most authoritative references I can
find--international standards bodies and the like) so if you see
something unexpected, odds are there's a reason for it. I'm always
surprised when I dig in and research some of these units. If you see a
conversion that seems surprising, I'll bet all the money in my wallet
that it's right, and there's a reason for it.
As a corollary, I've probably found and reported as many typos in
NIST publications as anybody out there. :)
Thanks for the question, though! I get this a lot. I've seen
various web pages where someone runs a similar calculation through and
blames roundoff or something when they should blame surveyors. :)

I just verified that the current version of NIST Special Publication 811 (linked above) *has* been properly typeset to indicate the correct definition of acre, survey foot, etc., which matches Frink's definition, of course. See section B.6. It also discusses the history of the "statute mile" and "survey foot", so you can prove to yourself that Frink's exact rational number is, indeed, the correct answer.
It's often, no, *always* necessary to do your research on units of measure with official, authoritative documents from your national or international standards body, and not believe the vast number of confused and poorly-researched sources out there. (But I'll repeat that for a couple years, even NIST had it wrong when they changed typesetting programs!)
As I said before, I'll bet the authority of Frink's research against any other unit conversion utility out there any day. If you want to be right, use Frink. I've noticed that other unit converters like the Google Calculator and Wolfram Alpha are very poorly researched, and don't understand the difference between many units like these. You can prove I'm right by following the definitions set forth by international standards bureaus.
If you want to see how a unit is defined, I highly recommend peeking into Frink's standard data file:
http://futureboy.us/frinkdata/units.txt
Nicholas had a good point when he stated that if a conversion came out close to a whole number, you should think about more deeply. However, as you can see, common sense has little or nothing to do with institutional inertia of surveyors, so you have to do a bit deeper research to get the *right* answer. :)
