Exactly. It's kind of annoying to see that omniscient overlords are censoring people's comments -- but the people being censored get the idea that their comments aren't welcome and then they either shape up or go away. HN has stayed pretty readable as the once-enjoyable Reddit has become the biggest cesspool of stupidity I've ever had the misfortune of reading. (Can you guess by my tone that I used to really love Reddit but it's just not good anymore? It makes me sad.)
