FWIW I (as the editor of LWN and the author of the article) do not mind the posting of this link. It has brought in 16,000 people (at last count), many of whom are probably unfamiliar with LWN. Some subscriptions have been sold in the process.

Certainly I don't want large amounts of our content to be distributed this way, but an occasional posting that puts an LWN article at #1 on HN is going to do us far more good than harm.

(That said, I do appreciate your concern!)
