On the Main page, there's a "New" tab at the top, which displays all posts in Main, newest first. That's the URL I have bookmarked, and if I happen to come in via lesswrong.com, that's where I go first. I'm theoretically aware that there's a URL to everything all mixed together, but I've always preferred to read Main(new) and Discussion separately.
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?
