Ana Marie is apparently going to read David Denby's illiterate and factually challenged book of nob-slobber, Snark. She starts by listing all these things that Denby believes "snark" to be. Some are right there on his title page. Snark is mean! Snark is personal! Snark is ruining conversations!
In short, snark is and does many things. But everything snark is and does, land mines are and do worse. And the world could make better use of a book about landmines. Even one written by a complete idiot.
