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.)
This might not be a valid concern, but I wonder as the number of Forum users grows if there will be so many posts that most of them can only be on the front page for a very short amount of time. Most posts would then slip under the radar and get very little attention (at least compared to now). This may put people off engaging - although I guess this would then mean you'd settle at some sort of equilibrium.
Lots of very short posts could exacerbate this concern. Maybe the forum has to adapt as it grows. Various sub-groups, like Reddit has, could help allow more posts get attention from those who are interested in them.
But as long as a large fraction of this small % of people sees the post, this is not a big problem, no? I imagine that this is for example true for EAs interested in improving institutions and the landscape analysis of institutional improvements.
