... We do what I suggested. We tighten the grip on any low quality post, irrelevant if they have a signature or not. The only way to do this that I can see is create a solid ruleset on what is and isn't allowed in a post and enforce that ruleset strictly. This would be the only way to deincentivize low quality posting.
Would be a huge leap forward.
Odd that a community with so many coders, i.e. people who work with and understand closed formal systems, seems set against doing just that.
The fact that a post is "low quality" or "irrelevant" is very subjective, and human judgment needs to be made to make this determination.
