I thought the fact that the grandparent was posted 20 times within 5 seconds made the meaning rather obvious.
It. Is. Too. Easy. To. Double. Post. Comments.
Many people do so accidentally and in fact it is the case that yesterday there was a list of about 50 most recent comments that were all multiply posted. This is a bad thing. I cannot make this any more clear and would not take further incomprehension of evidence that my meaning is not clear.
I note in myself a tendency to see some things I don't understand as "extremely bad", stupid, frustrating or etc., especially things that have changed recently from what I am used to.
Allow me to revise this. I can, in fact, supply instructions on how people are most likely to double post comments.
I saw some discussion posts earlier talking about a LessWrong redesign, and now that things look different, I guess that it's been implemented. I'm always slightly annoyed for a while when a site I use gets redesigned because I have to relearn where everything is, but it eventually wears off once I'm used to the changes.
My initial impressions:
"Hmmm... it seems like the category menus have been replaced by dropdown menus. It's not like I used many of them anyway."
"Okay, I've clicked my name to see my recently posted comments. Now, where's the link to see it in context? Oh, I guess I have to click that icon in the lower right corner. For some reason I was looking for something at the upper right of the comment box."
"Well, that worked. Now how do I click to the parent comment? Oh, wait, it's probably one of those new icons in the lower right corner. I'll just mouseover them to see what they do..."
::realization sets in::
"AAUGH! LESSWRONG IS USING MYSTERY MEAT NAVIGATION!!!"
So, what does everyone else think of the new redesign?
