For everyone seemingly in agreement that it's bad, I don't see a lot of tackling of the question "why?"

[i]Why[/i] do so many people conflate quality with quantity? As someone running an RP in the advanced section that seemingly has not incurred this problem to remotely the same degree as the cited examples, do I just have really wonderful players or is there something that provokes this (and by extension, can be done to avoid it)?
