It looks like with Slate's latest revamp to their site's U.I. last week, the Bad Astronomer's blog posts no longer have a way to post comments about them. (Slate's new look allows for a dark magenta "comments" button at the bottom of a blog post, next to the share buttons for Facebook and Twitter -- but Phil's blog posts don't have this dark magenta button.)

Was that Phil's choice, or did this just slip through the cracks?
