Sounds to me like you are seeking to evaluate ideas solely on the basis of the posters in-game achievements, which I think is overly limiting. Who cares how many times the poster's beaten the Shroud on Elite? I care more about how the posted information can help me. Less experienced posters can sometimes come up with the more creative ideas, because they're not mired in "this is how it's always been done" mentality.
Those who demand civility would do well to first extend it themselves.
