If you watch the frequency of close votes, I presume you would find that close votes cause close votes. That is to say, a question might receive its first close vote on its third day of existence, only to receive 4 more close votes within the ensuing hours. This tells us that one user is far more likely to vote to close a question simply because another use did, which means that the motivation for each close vote cast on a given question is less likely to be based on original thought. It also means that a proper, unbiased consensus cannot be had.
This is conjecture, based solely on my own observation. It's not a bad idea, however. Imagine how presidential elections would go, if votes were tallied on the wall outside voting booths, in real-time? Why should we think that the motivation to close questions on a Q&A site is driven by an entirely different psychology? Mob mentality is ubiquitous in human nature.
