Meta post: Did something go wrong?

There is a post at this link: http://​​lesswrong.com/​​lw/​​mp3/​​proper_posture_for_mental_arts/​​

It does not appear in my discussion feed. See the timestamps in the pictures below:

and:

It’s currently 0900 local time on the 1/​9/​15. The only reason that I can think of this being wrong is that its a timezone publishing effect. But I don’t know how, or what to do about it...

It also does not appear in an incognito window view of the discussion.

Now what?
