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.)
I agree. While I appreciate the push to lower the barriers to posting for those who feel intimidated, the flipside of this is that it's pretty demotivating when a post that reflects five months and hundreds of hours of work is on the front page for less than a day. I feel like there's something wrong with the system when I can spend five minutes putting together a linkpost instead and earn a greater level of engagement.
