@colmweb.org discussion period ended, and now we entered the meta reviewing period. It's not simple getting reviewer engagement nowadays, but slow and steady we made descent progress, even if shy of the ideal of early and wholly.

I am not convinced this is the best way to compute this, but here goes. Definitely n per reviewer is too small to get anything meaningful

Help me understand why it's different than "my multi-step decision process model is not perfect (i.e., biased), so it introduces bad/biased decisions into the output"... because I don't know if I want to start using "sabotage" instead of "error" in my papers

No surveys here, so I ran this on X. So this brings about the next question: why are we still doing two columns in some venues?! Or tiny fonts in others?
We need templates that fit how people read: fonts, columns, margins, etc
