@ GW - I am in it strictly for the peanut gallery value, if it is useful to SD, so much the better!
@ Sammual - I totally agree - looking back over the last survey I thought it was pretty good, but there were a few questions I fetl were worded badly or were not clear. I was kind of doing it on a whim anyway, if I continued doing them I would put more thought and care into the wording.
I think I will probably at least do one tomorrow, see if the response is on par with last week's, and continue doing them as long as there is sufficient interest and/or I can keep coming up with questions that (at least I think) are interesting.
