This comment is a bit out of date (though I think it was made before I made this edit). The current language is:
Posts that focus on the EA community itself are given a “community” tag. By default, these posts will have a weighting of “-25″ on the Forum’s front page (see below), appearing only if they have a lot of upvotes.
We don’t hide all “community” posts by default, but they will generally be less prominent on the front page unless a user changes the weighting themselves.
