No one's paying attention
This is just another example of what happens when no one pays attention.
Some other examples from personal experience, not entirely IT related, of the results of no one paying attention:
1. A weekly e-flyer for a pharmacy chain, in PDF format, but really just a string of jpegs with such low resolution you couldn't read the text. No way to tell just what this week's specials were! No one bothered to actually look at the end result to be sure it was legible. Strangely enough, an email to the president's email address actually got to him, and they cleaned up their act promptly. I imagine somebody got their fingers slapped over such stupidity.
2. A big illuminated sign by the highway saying "For latest road condition information, check http://....." With all the hoopla about the adverse effects on driving of using cell phones, you'd think that a sign that was an open invitation to fire up your browser would be dismissed off hand as counterproductive.
3. An emergency response program that has designated routes for emergency vehicle use only. Problem: all the routes between different parts of the metroplex are so designated: you simply cannot get from part A where people work to part B where they live without using one of these highways. If we have a big earthquake (certain to happen sooner or later), everybody's going to want to rush home to make sure things are okay, that their kids in school are okay, etc. There aren't enough cops to block the resultant flood of traffic; and besides, the cops will have other things to do after a big shake. [The city I live in has very few road links between some sections.] This particular stupidity also involves failure to take into account human nature which, as the old adage teaches us, never changes. Plus the common bureaucratic position that making a rule against something actually stops people from doing it.
In the present case, somebody didn't bother to look at the email address they'd keyed to be sure it was correct, to say nothing of the other criticisms of this fiasco.
