Recently I've seen alot of threads where people just jump into writing an incredible episode without putting their readers into consideration.
I'm not a fan of reading very long articles and most times I think some posts ought to be simplified and summarized to get ease of attention and from my observation, it seems most users confuse quantity with quality and think, writing very long post simply means the post has quality which is wrong.
I've seen very short and straight to the point post doing extremely very well on the forum and people ought to them learn from them.
Basically it's about orientation, most persons have got the orientation that they must make a length post to gain attention enough and merits probably because they think quantity means quality meanwhile it's not applicable in most cases, like you rightly said some straight to the point post even gat more quality than some episodes.
I think this post is most applicable and important for newbies so they can be properly oriented, in a bid to get a writing pattern they should also have this at the back of their minds too.
