What behavior changes would you want or expect?
None. I want nothing, because I am fine with the natural order. Besides, other people's inclinations are not subject to my approval.
I think you'll find that people are probably taking this more seriously than you'd think. It's an important step to acknowledge an issue, and like 58 threads into this I think we've brought some attention to it. I'd bet you're going to see some small changes around here, and will probably see a lot of people consciously try to reply more to newer posters.
At least until they forget. But, you are more the optimist than I am.
That being said, 1-10 scale: how tuff are you?
How tuff... let's see. If a crowd was taunting me at the line, I'd hit both shots and then turn around and dump a bonus three-pointer on them, no extra charge.
