I didn't downvote you, but I guess I just don't get it. Here's the guidelines, seems like this one pretty clearly stands in the on-topic realm of things.

"On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic."

"If your account is less than a year old, please don't submit comments saying that HN is turning into Reddit. (It's a common semi-noob illusion.)"

Not quite... when digg/reddit get it it'll be cut & pasted onto someone else's blog with ads all around it.
