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.

EDIT2

This feature was proposed for the wrong reasons, when I should've "counted to 10" if you will, and proof that correlation does not imply causation. As a few of you pointed out correctly, just because a lot of 1st-time questions are abandoned by their author, it doesn't mean that all 1st-time questions are a waste of time; it's up to you to decide whether or not you want to spend time answering a question or not, and that takes more than just the user rep to decide.
