One thing I'd really like to see is less tactical flagging of content.
Hopefully with your additional help, people who suppress content they disagree with will be kept in check.
Open discourse is something that used to be sacrasanct in scientific and engineering circles. Over the last decade or so, free speech has been on the decline, and discussion is now very polarised along political lines.
For example, it's nearly impossible to discuss technical progress made by Elon Musk's companies without brigading by leftwing commenters, and I've seen positive news about Musk and his companies get quickly flagged and squirreled away. This is self-serving behaviour by bad actors and should be addressed in order that HN is a politically-neutral forum for discussion, and not a leftwing echo chamber.
