The “conceptual neatnik” (
) in me agrees. There are times when I have found the more freeform nature to be a bit messy.
However, (A) I have also come to really appreciate the fertile cross-pollination that sometimes happens here that categories and sections would no doubt hamper; and (B) my experience from more compartmentalized forums is that in practice many posts ooze across the boundaries anyway, making the compartments themselves all the more annoying for being violated.
