A nice idea but I don't know if it would work. In a "perfect" world, people would think "Hey this is really slick, I'll give it a 10!" However, the world is far from perfect and even farther are the people.

The rating system would probably get abused. There are people here that would down rate anything that they perceived as being a waste of their time. There are people that would downrate because they think that person is a complete moron. Heck some people would even downrate stuff because it is an area they don't like(unix vs pc for example).

How many times have you seen people post something silly or argumentative and get blasted?

If rating was to get installed, I would think it would be a "balanced" group of people that would vote the ratings rather than the open community.

Some questions might be a waste of somebodies time but to a bunch of noobs, the information is priceless.

So ++ for the idea but I would probably -- the vote as I think it would only create more elitism then solve a problem.
