Your comment is hypocritical. This is to say I'm sure you point is made elsewhere, somewhere. And yet I'm glad you posted it so it can be discussed. Which is to say it's still wrong even when applied to itself (a wrong point).

The point of discussion isn't to create some sort of internet that might one day be studied and determined to contain useful information, the point of discussion is that those who participate can learn and improve. Sometimes this necessitates saying things that have already been said. That's not a problem.

As for the notion that sometimes discussing things with people in significantly different circumstances to yourself might not be the highest value discussion you could have, I agree. However it's still fun, interesting, etc. Better use of time than Netflix, that's for sure.
