In reply to SirCallum:
So...I find this sort of thread to be surprisingly frequent. (Getting UKC to fill out surveys).
I presume each data collection request is separate to the last, and that the previous survey raw results may not always be made public?
It seems to me if UKC had a spot where raw survey data was dumped, it would give people doing survey's a much bigger information set to work with, and over a long time scale the ability to observe historical trends.
It wouldn't be all that hard to pull off, merely the agreement that each new survey request posts its raw data to some designated spot on UKC.
It could even evolve one step further, that we have a once a year the official grand UKC survey. Shortly after would be a state of the UKC community article, which be a simplish analysis of the survey results.
(Many other communities have similar things, so everyone gets an idea of trends and what everyone else is up to).
Just throwing out an idea.
