The worst part about their worthless surveys is that it's pretty much impossible to give feedback about the actual survey itself.

It's easy to see how this happens; a clueless exec at big-corp decides they need data, survey company gives them a sales pitch they can't refuse, exec never bothers to actually check out the product.

These worthless surveys are almost exclusively on the websites large enterprisey companies that got off the clue-train years ago.
