Of course, the point of all of this is to gather enough opinions to actually sway the way the game develops in the future. Hopefully, with questions dealing with how much we like to "build" items with parts (bookcases, double beds, etc.), and the option to say that you don't like it at all, we may actually see a lessening in those kinds of items, if enough users agree. You can even rank various gameplay features (decorating your house, visiting friends, customizing your Sim, etc.) in the order that you like them. In this way, perhaps we'll see more focus being placed on the most (overall) liked feature, and you'll be able to say you helped to make that happen.
Unfortunately, this isn't the kind of survey that will allow you to give your opinion on future item sets, but there are plenty of blank text boxes for you to say exactly what you want to the developers in a place that you know they'll see it. Again, this survey is prety lengthy (when compared to other Facebook game surveys anyway), so you'll want to make sure you have around 5-10 minutes to set aside to take it.
We've taken this survey as well, and if we start to notice any gameplay changes arising because of options listed here, we'll make sure to let you know. In the meantime, head over to this link right here to take the survey for yourself.
