Taking this to Banter...
When I think about it, I generally agree with you. Neither type of post is great to have to scroll through when there are tons of each. But generally the "doom posts" tend to overwhelm most everything. I get just as down or frustrated when there are model cycles that seem to look worse or trend worse, but I don't feel the need to dump a ton of what I feel in the main discussion threads. That kind of stuff should be put here in Banter (or the semi-defunct Panic Room?). I'm just as guilty as anyone with putting "banterish" posts in the main threads, though generally I try to keep those a bit lighter with some humor. There is a certain amount of leeway in what one can post in those threads, which is totally fine (outside storm mode, when we have that). Especially in the "down" periods between model runs. But I also try to put some things here in Banter as well instead of the other places.
