I sometimes hear that someone doesn’t want to post an idea because they feel like they would have to write a whole post, and it would need to be long, complex, and fully fleshed out.
I think short and simple Forum posts are fine — in fact, it’s often better for a post to be significantly shorter. (You could also consider making it a Quick take.)
Jup, would have been even funnier if the post content was just ".", but perhaps this wouldn't have helped that much convincing people that short posts are ok. xD
