That's a fair question considering TC is all about the conversation in the comments section.
We ran in to some unexpected issues with upgrades to WordPress and Disqus this week. We're working on fixing the problem and we appreciate your patience.
(Thursday morning update: The comments are back, even though it says "0 comments" under each post. For now, if you click on the "0 comments" link it will take you to the list of comments for the post. We're still working to get eveything back to normal.)
