Here is my take on the subject.

There are 1517 instances of @rev

of those:

"made" occurs 83% of the time (1259 instances)
"stylesheet" occurs 8.2% of the time (124 instances)
The rest occur 8.9% of the time (135 instances)

the misuse of "stylesheet" is trivial and only a matter of informing 
authors of their error, the fact that a high amount of authors are using 
rev-made is Inspiring to say the least, because every made link type is 
a claim of ownership, not authorship two totally different semantics.

I will study the results of @rel soon but from first glance It seems 
there is (statistically) more abuse and misunderstanding about @rel than 
there will ever be than @rev
