Meh. I don't want HN to be like reddit. For one thing, we already have reddit. For another thing, it's been overrun by the snarky eternal September hordes.
I think the reddit vote hide command is actually legitimate. I think reddit should provide something like that so you can say things like "I don't want to see anything about Sarah Palin".
I know that's what the recommendation engine is supposed to accomplish, but it doesn't work all that well.
You're not thinking like an avant-garde social personal active markerting entrepreneur, you don't need a botnet you just steal visitor cookies as you go along...make it so every visitor votes for you.
//really hoping I didn't just give someone an idea.
