If my understanding is correct, votes cast represent how useful/good a particular question or answer is.
Why is it then that the total sum of votes on all answers to a question don't contribute to the question's total score/vote?
As the answers suggest, the real problem here is that while some people look for good questions to answer, other look for good questions to read.
The first group of people, I believe, use the "Active" and "Hot" site sections, while second use "Week" and "Month". I myself subscribed by RSS to most of StackExcange's sites "Month" sections, and what I expected there, are good questions and good answers in them, not just good questions.
So, why not change said sections that way? Or even design with both groups in mind and split the tools for finding questions accordingly.
