Questions that have a score of more than 10 do not help the definition of a site, they simply gather points as people are less and less likely to look down the page to see if there are any other good questions and its usually that the first question with score of 10 will gain most upvotes simply because it was first not because it was excellent. That said other good questions might suffer from lack of attention.
There is a very easy fix questions with score above 10 should be sorted in the reverse order. The highest voted questions should be last the lowest first. (so first all the tens and then elevens etc)
Questions with score above 10 should be hidden by default.
Questions that didnt reach 10 votes should be sorted like they are now. with highest score first.
That said i still think we should have an option to sort questions the way they are sorted now (or if we decide to hide the questions with higher score then there should be a button to view them) but with the higher vote questions out of sight by default.
This will make it so proposals move along quicker. And will not hinder the attraction of the proposal because as I stated earlier top voted questions are not necessarily most interesting questions on the proposal just been there first
