Myself, the main concern was the volume of post by LSU fans about LSU football on a board I read for Alabama football content. Sometime, the subject matter had very little if anything to do with LSU football. Some threads would get buried under threads about LSU football. And as is a habit of a lot people, they could not let anything slide. If there was any criticism about Coach Miles or LSU, we would have three or so posters who would without fail respond and would keep going until they had the last word.
That being said, I genuinely liked the LSU posters on here; and as someone who tends to view sports in a spaghetti western style, I appreciate the counter balancing views that other fans provide.
One last thing: I think anyone who post over here and then puts quotes on tiger droppings that ridicule posters over here should be permanently axed. Moreover, it was hinted that posters were doing that in the past, and I would not invite those people back. There is a soccer forum that I read that has Mexican and US sections where the Mexican side has a "Gringo wall of shame" thread. Being a neophyte, I do not have that much to say but it discourages me from posting over there. Its not the worst thing in the world, but I think it is two faced and classless.
I've always think of this as Bama Nation's house to do as he wishes. But since your asking about who you should invite over to talk football, these are my two cents.
