Would like to see the ability to hide the questions that are visible to me if a question is asked by a user with a reputation lower than a threshold set in personal preferences.

EDIT

I meant as a personal preference, to be able to hide which questions I see. This is similar to how Slashdot does it: you can hide comments that are below a certain threshold, but this in no way impacts what others see. Obviously by default this would be disabled.

Why? To see more meaningful, rewarding questions to answer in the first few pages; to eliminate some "noise" if you will.
