Dionaea posted a RoM/Gaming survey today :

While the survey questions are nice, like "do you think the community is satisfied with RoM?" (we all know the results of that though :p), it didn't have any questions on player opinion regarding IS and IS offers, which is a big source of player discontentment at the moment.
So while they can get results on whether the players are content with the current state of the game, if the results show that players are not, they won't really know that a lot of that has to do with the IS (correct me if I'm wrong here).
But +1 to the questions about bug fix speeds. Maybe the results will motivate them fix up bugs faster in Chapter V
