People who use words wrong tick me off. Right now, my biggest peeve is people pretending that "data" is an ordinary plural noun, instead of treating it like a mass noun. Now, I realize there is some debate on this issue.
But this I ask of you; If all the following are wrong:
- The water are filthy.
 - The wood are being chopped.
 - The furniture are broken.
 - The information are incorrect.
 - The money are being mailed.
 - The meat are cooked.
 - Their knowledge are vast.
 - The software are being developed.
 - The laundry are dirty.
 
... Then how the heck can "
The data are missing" be correct?! >:o
