I tend to not listen to people if they are under level 12, but once they get into that stuff I start reading more of their posts, and other things, like clicking on their profile or something.
It's mainly because low levels are just noobs and still don't understand the BBS as a level 16 or some one would. They often make short, one-liners or don't think about their posts just so they can get their post count up. I personally have been convicted of this.
But when you start being here longer you respect people more you'll start not caring about post count and more about the structure of your posts, whether people will read them since their so long, and how you fare will other good-posters.
