Remember those 3x5 cards at Studio 60? Studio 60 always has more cards than will fit on their board. If something does not meet your blog's standard for quality or interest do not publish it. You might send something back for rewriting or additional work. You may decide that an article does not belong. You might even decide that an article has a bigger future somewhere else on your website, in your printed newsletter or in an industry publication.
Studio 60 is a good show by the way.
