It mentions the Libertarian over-use of 1984. I've always found this especially ironic, because Orwell was a Marxist who fought with the POUM in the Spanish Civil War. Granted, a Libertarian Marxist, but I rarely see the types this FAQ is addressed towards willing to make the distinction.

And this is unrelated, but I always like to add a nod towards it, if you enjoy Orwell's work, pick up Homage to Catalonia. One of my favorite books, and even if you disagree completely with Orwell's politics, his writing and storytelling is extraordinary.
