The other thing that never improves threads is everyone only posting what they think might get upvoted instead of saying what they actually think, especially when there might be a grain of truth in it. Tedious comment back-patting is the death of good communities.
Everyone's gotta cool it with that meta-modding too. I'm sick of scrolling through tons of knight-in-shining-armor comments to get to the actual discussion tucked at the bottom of the page.
