The other problem is that the responses will be skewed depending on where you choose to advertise this survey and who's more passionate about taking it. Posting it here would likely trigger responses from those more inclined to say "rss is not dead", since that's what the overwhelming sentiment is here.

I can only conclude that you likely already know the survey is pointless, but it's being used to advertise for your RSS reader (you plug that in on multiple places on the site). You'd probably be better off just advertising your RSS reader instead.
