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)?

Theres more skill in telling a story with fewer words and achieving the same goal. Lengh and post size is not the only factor of qaulity. Telling a story In 300 words we'll and effectively, is better than 1000 words with 400 of lore dump and another 100 of padding. 

Lore dumping for hundreds of words, eh. Telling it as part of a well woven story, linking charecters and past organicly. That's qaulity.
