why does it seem like the same people respond to every fluther question?

I’ve noticed some of you complaining about ignorant questions being asked and trying to come up with methods to weed them out. I can’t help but notice when I get onto fluther and click on certain questions to obviously read over community input and to possibly input myself, it seems as though several fluther junkies tend to answer every question. Now you want to root out idiotic questions but what about getting input on topics from more than just the regulars?
