For one, I have not seen the the discussed thread so I do not get anything of what is going on here. (That is what happens when you leave your computer and go away for the yuletides.)

But second, I get little information from the yelling part. And generally it tends to deteriorate into one-up-manship and take the form of a game where it is about winning and not understanding. Some find it funny. As a rule, I do not.

For an example of how bad it can get I recomend this video. (And also because it is quite funny.)
