I've seen a lot of otherwise reasonable threads get bogged down by "lowest common denominator" replies, especially ones that don't require reading the article and could really be posted in any thread matching the right keywords. Such comments are *really* easy to make and frequently do "well" in that they attract votes and comments, drowning out the rest of the discussion. Do you have ideas on how to combat this? Obviously moderator intervention would help, but it's not possible to be everywhere, especially in the first couple minutes of a post when the temptation to leave a lazy comment and the cost to the overall direction of discussion from such a comment is the greatest.
