The survey team spent some time discussing the pros and cons of formats for a 
number of the questions in the new survey.  I think when we initially sent out 
the first draft of the survey, that specific question was simple checkboxes, as 
I think it had been in the previous year’s edition.  The final survey looks 
like this:

There were several factors that influenced our choices.

One is a disinclination to force a strict ranking of items for which ordering 
isn’t natural.  For example, one might favor one resource to discover context 
for option settings, and another for explanation of error messages — is one 
more useful than the other?  When a respondent had not previously been aware of 
some of the choices, how does she legitimately rank them compared to others?  
This overlaps with the realization that stack-ranking of employees is at best 
contrived and at worst harmful: diverse sets of talents are complementary, and 
“different” usually != “better”.

Another is that the survey is already long, demanding significiant time and 
energy to thoughtfully complete.  Rankings require extra thought and time, 
which can be in short supply when one just wants to get through the darned 
thing and get back to work and/or a plate of garlic fries.  One  contributor 
observed that in a long survey especially, respondents are likely to just stab 
at anything to get to the next question, vs. ardously comparing each pair of 
values (bubble sort!).  This phenomenon grows as the number of choices grows.  
With two choices, it’s not too bad; with 10 it’s a pain.  “Okay I’ll rank the 
first item as 3.  Oh but then the fifth item really is 3, so I need to go back 
and change the first item to, um, 4.  But the third item really is 4, so ummm 
…. "    This can lead to lower quality results.  Consider Arrow’s theorem:  you 
can’t have an ideally rational democratic social aggregation device.

By reducing tedium, we aim to get better results while also improving the 
experience for the respondent.  As we reworked the entire survey, we strove to 
maximize both value and ease of participation.

For certain questions we settled on the matrix format shown at the link above.  
This lets us capture the value of each resource as an absolute, rather than 
coercing an (artificial) relative value.  It lets the respondent consider the 
value of each resource independently of the others, while also decreasing 
tedium.
