Attention Persons of a Jaunty and Polished Demeanor

Now that Jeff McNeil has moved on from the "blog," he has more time for actual writing. He sent a wire to the "blog" a few days ago asking for some particular writing advice. I gave him my writing advice. McNeil then explained, via semaphore, that he wanted not MY advice, but that of the kind of person who reads my "blog." I suppose you know who you are! What McNeil wishes to ascertain, in short, is this: having printed out several copies of his novel, should he send the copies directly to publishers? Or would agents be more appropriate targets? Or should he, perhaps, send half the copies to publishers and half to agents? Well?
