This, I absolutely agree with.
I often put disagrees on posts which I think are wrong where someone else has *already* written out why it's wrong. Rather than spamming the board with yet another debunking.
only problem with this approach is that -- while annoying to everyone that actively follows the board -- there's so much traffic that repeated debunking is the best remedy for someone to actually see it. You can stack twenty disagrees on a post, but then you have to do it again on the next smokey bird post.
Part of the goal of trolling is to destroy a resource. They don't mind getting a hundred disagrees (especially if it starts firing up people's emotions) and they don't mind posting the same drivel over and over and over... Anything to increase the noise.
Am I doing that (adding to the clutter)? Sigh. But I think these meta discussions are important.
Personally, I don't use "disagree", ever. If you look at my profile you'll see that I've given one, not sure where/how that happened, but it is the only one. In a healthy forum the disagree would serve a useful purpose for gauging community sentiment on something.
However, despite my personal sentiment, I am glad that some people are using disagree. I don't think my approach is the only one and I think the board is better off for their being different posters with different perspectives and different approaches. So, while I do think there's a problem with your approach (as outlined above) I think there's a problem with mine and anyone else's. I think its good that people differ.
So the fact that we have a mix of disagrees on poor posts combined with debunking posts is, IMO, overall a good thing. To reduce noise in the forum requires effective moderation. Which is being done by volunteers and is a thankless task (you won't catch me offering to do it). I'm not criticizing the valiant attempts by the mods.
Also, IMO, this thread is kinda special. It has such high traffic that it is quite useful in terms of getting responses (as other posters have already noted), though this means it is rarely topical. I get the impression that at least most of the posters have an interest in market action and the high activity here is a reflection of how interesting that is. But people find it easier to track one thread rather than the twenty whatever that are contained here. I will admit, I read far more different threads before I joined and started posting.
Boy, I really feel like I've been rambling so I'll try to give a coherent summary:
IMO --
1) repeated debunking increases noise, but still has utility
2) focusing on disagrees has utility, but doesn't compete well
3) my approach isn't yours, but diversity is good
4) thank god for the mods
5) high activity and non-topicality are inherently interrelated
