On the Willow Smith article on the mainpage there's actually real discussion going on, but you'd never know it glancing down at the comments, which look like this:

Thank you, Author's Discussions for making us all look like ... that.

Edited to add: This is no haterade on contrarianist or zeetyrwhitt — everyone's allowed to make inane comments. It just blows that the platform highlights comments based primarily on author participation when the authors don't have the time or energy to (or whatever possibly totally legitimate reason) to bring forward the better discussions.
