Dang is going to have 65,535 karma points soon

Not much.

dang explains most of the privileges / thresholds in various comments over the years:

Karma > 30 enables flagging and vouching privileges on posts and comments. <https://news.ycombinator.com/item?id=14697607> & <https://news.ycombinator.com/item?id=24134548>.

Karma > 500 enables downvotes on comments. <https://news.ycombinator.com/item?id=10224653> (Posts cannot be downvoted.)

Sufficiently negative karma causes an account's comments to be autokilled. Threshold not specified. <https://news.ycombinator.com/item?id=16409493> (Profiles can also be banned specifically by moderators, e.g., <https://news.ycombinator.com/item?id=35426426>.)

The 100 profiles with the highest karma are listed on the leaders page: <https://news.ycombinator.com/leaders>. Currently the 100th-ranked profile has 40,270 karma. There's no special privilege other than being listed, no member lounge or secret handshake.

(You can figure out most of this by searching for dang's comments with appropriate keywords, e.g., "by:dang karma threshold", which turns up most of these. I'd also looked for "vouch", "downvote", and "flag" specifically. <https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...>)

I agree. There is an unofficial list of undocumented features maintained by minimaxir https://github.com/minimaxir/hacker-news-undocumented

After 250 you can also set your topcolor.

Or with no limit given a CSS manager / mangler :P

Recent local tweak highlights mod comments as well:

  /* Highlight mod(s) */
  .comhead .hnuser[href="user?id=dang"],
  .comhead a:link.hnuser[href="user?id=dang"] {
      color: #ff6600;
      color: #dd5500;
  }

I'm aware that HN prefers to deprecate author over message. I disagree with that somewhat --- context, authority, identity, and reputation matter. Note that HN does distinguish new ("green") profiles.

The other HN superpower, available to anyone with an email account regardless of karma, is to email the mods. That's how I started interacting with dang, and still do generally a few times per week/month, mostly for mundane stuff (titles, link disambiguation), occasionally to vouch killed stories, or to point out spammish or hostile behaviour (rarely on the last, flags really do most of the work here).

That's a really good list, thanks!

(I'm familiar with ... all or nearly all of it, but a one-stop-shop for HN features and behaviours is quite useful.)

The points= parameter is quite useful, and one I'd either not known or forgotten. E.g., posts with >100 votes: <https://news.ycombinator.com/over?points=100>
