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.
Not pointing any fingers because that's the truth where signature campaigns requires certain number of characters for it to be counted and some doesn't have. Well, some posts does indeeed written in details but some people will do it in summarized version but still in good quality or you can say, it is like the same as the detailed version when as you can see it is summarized. Some people doesn't want to read because it's too long or only read some lines or maybe TL;DR in short.
