I wonder if anyone else misses things
Yes. The current setup is not ideal.
It's a half-tier between discussion and main attempting to alleviate scaling issues.
A better solution would just be to implement a full tier between discussion and main, or to create a new tier above main. Sample proposal (I'm not going to do this, so I don't expect anybody else to do this, this is just an example structure):
Discussion remains as-is. Main is consolidated into a single tier. Promoted is created as a tier above Main, with some multiple of the karma values, but requires a buy-in of, say, 500, or maybe 1000 Karma Points for each post placed...
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?
