Emphasis mine. Can you make a case for it being "abusive" in the context of the full text? I take it to mean generating an excessive number of links, not posting one link to a wide audience.
Separately, there's pretty much no better linux news source, and imo subscription is worthwhile.
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!)
I think that this may convince me that I need to move it up higher on my list of priorities!
I read the kernel page and front page religiously, and read bits of the others.
I can't imagine how many things I've learned following the kernel's development. But the mailing lists are HUGE and thus hard to follow. LWN makes keeping up possible.
