Well I would think pg has thought it through, but there are a lot of newbies on HN as evidenced by the sudden use of OMG and LOL that was absolutely not on HN before his "Kill Hollywood" essay.
Y'know that book "Fifty Shades Of Grey"? Well that's what your comment's gonna go through in the next hour if you disagree with (I can't believe I'm saying this) the hivemind.
edit: Also, what's with this new "You're submitting too fast. Please slow down" message you get if people start downvoting your posts? I've had it swallow a bunch of (intelligent) posts this morning due to the fact that I expressed an unpopular opinion on a copyright thread.
That fucking does it.
