I wasn't using 'patent troll' or any of the other terminology. I was pointing out a flaw in this guy's reasoning. Yes, I had only read 500 words into a 4000 word article. I'm now about halfway through and have scanned the rest of the article... and I don't see anything that invalidates my claim above. IV is not the 'market' that it says it is. If anything, I am supporting what npr is saying.
HN moderation is weird.
I've seen this elsewhere - if someone says they're being sarcastic, they're downmodded to hell... but people in the same thread saying the same thing in the same sarcastic manner, but without the admission, are left alone.
I find this inconsistency annoying - it appears that downmod-friendly HNers are more interested in making a pretense to politeness than actually moderating content. It only takes a single dissenter and your words are already diminished on the page.
