It's not about how long the article is because it's all about how the message is conveyed like getting straight to the point. Well, there are some people who make the article going in circles before getting to the point. There's also some who did it because they are required to do so since some signature campaigns have rules like # of characters for it to be eligible because if not then the post won't be counted or not eligible to be counted.
I agree with you. However, whether a piece of writing is judged as quality or not depends on its content. If it is long but meaningful then that is also good. However, if the writing is related to technical matters, it might be better to just answer as necessary so as not to confuse things. However, when discussing opinions, it is necessary to explain and give examples so that the argument seems longer
I get your points mates but I wouldn't have to point fingers at signature campaign requirements when making extremely unnecessarily long post because most campaigns always ask for 150 character and some ask for at most 200 characters and if you're to judge that, I think about 3 to 4 line post would give you upto 150 to 200 character writings without necessarily writing a full episode.
There are post that actually don't require stories because people want to learn and there are post that would require you to write in details and my point is that, we should wirte in details when needed and be brief when due.
