I have noticed an usual trends lately in the discussions board most especially Bitcoin discussion, gambling discussion etc, members rush to make a short comment just to reserve the first spot on the page, and after a while coming to edit it with the full text, this make no sense to me, and no signature campaign demands that you must be first to comment at least none that I know.
The effects of this is that, it limits readers from seeing your original thoughts on the topic because at first glance you see something like straight forward answer like (really), and when edited to contain the full text the reader may not come back to that thread again.
This happens mostly with those in signature campaign and I think there is need for readjustment, no need reserving comments space to appear on the first page.
If there is any thread on this issue already please let me know to lock this one.
To say that I've also come across some trend of posts related to their Short inputs just like you've said, It feels awful that lot of forum members are adaptive to Shortcut their threads in a half of incomplete with a logic of saving stresses and also stocking posts where they can just come back again to continue with it just because they want to meet up with post counts. Most especially ones in campaign.
I've also understand that other Forum members too who're not interested of reading through lengthy texts are cause of it because While I've been in the forum for awhile now, I observed that lengthy topic threads are hardly to have forum members complying to read and reply them even though it has qualities and making such posts feels discouraging because your efforts spent to create the thread that users ain't finding useful feels bad.
JJG has been a lot of good inspiration towards keeping quality posts without undermining the threads size.
