Hm. I'm seeing non-top-level comments there -- is it possible you hit the "top-level comments only" link and didn't realize it?

Try loading the entry in a new tab, and clear your browser cache first just to be sure.

(EDIT: As afuna and I collide! If she was seeing what you were reporting and I wasn't, that's more mysterious. Lemme get back to you. (But try clearing your cache anyway just to be sure!))

EDIT, again: nevermind, we figured out why I wasn't seeing it happen and fu and mark were! The comments will show up in site-skinned comment pages, just not in journal-styled comment pages. Looking into why that is now.)
