Re the concern about flagging, the situation is much as I've described in these past threads: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... Specifically, when I looked through who had flagged the current post, I saw the usual coalition between users who appear to be consistently flagging for political reasons, and other users who have quite different flagging patterns than that. In any case, virtually all of the accounts that flagged the thread were established HN users.
Sometimes when people bring this concern up, I go through and make a list of other stories that the same accounts had flagged, to illustrate the point that their flags are not exclusively targeting one specific topic or vector. I've done that here in a collapsed reply, if anyone wants to take a look.
I hope this explanation helps - your posts in this thread seemed to me to be in good faith so I wanted to respond in kind. If you still have a question that my comments and links to past explanations haven't answered, I'd be happy to take a crack at it.
Here are some stories that flaggers of this submission also flagged. I have no idea why, except for the handful of obvious spam, but it illustrates the point I made in the parent comment.
It seems that people, even "established HN users" will flag literally anything. Do you feel that there is any remaining article quality signal that can be obtained from the current flagging mechanism?
If the above list gives the mistaken impression that flagging is basically random, that's an artifact of the way I cherry-picked the list. The flagging system has problems, for sure, but it's a vital part of how HN's system functions.
If you squint and look closely, though, I think you can detect this in the above list. The weirdest "wtf?" cases of flagging are ones where the threads had a lot of comments and were on the frontpage. That means upvotes won the tug-of-war with flags, as they should have in most of those cases.
Conversely, it you look at the submissions in the list which had 0 comments or very few, it looks to me like most were either spam, low-quality articles, or dupes.
Remember, also, that some flags are just mistakes - the link is easy to fat-finger or misclick, and the UI doesn't provide feedback about that. That's likely to change soon as part of work that tomhow and I are planning.
