I second Aadik. I think that we (At least us North Americans) live in an era of being ignored. And as my momma always says "The squeaky wheel gets the grease."
So, it's not suprising that people occassionally find the need to repeat the same point over and over, ad naseaum before they think they're being heard.
But it isn't like that here. From what I've seen, Markus and the OOTP insiders here on the board aren't like that. They really do WANT to hear constructive criticism and they really DO listen.
I think sometimes it's easy to think that just because Markus and the guys don't respond to every post, they haven't heard us. But personally- I think his silence only means he's busy listening and thinking, instead of talking.
But I really find this "Like it or lump it!" mentality very McCarthyistic. When I read someone saying "if you don't like it go away.", I think of the bad old days of the Cold War where every desent was attacked with: "If you don't like it here, why don't you go back to Russia!"
