To my knowledge, HN hasn't added any new features in years. I think the people who run this site are pretty happy with it the way it is and don't want to change it, despite many suggestions for improvements. So I wouldn't hold my breath waiting for them to do anything about it.

Actually I added one about an hour ago.

This is an interesting suggestion but it would not be on our top 100 things to fix.

As accounts cannot be deleted (and I understand why), I would love to see the ability to change my username to something less identifiable to me.

Very glad to hear that improvements to HN are still being made. I stand corrected.

>Actually I added one about an hour ago.

What was it? I'm genuinely curious.

Better detection and banning of abusive crawlers.

Most likely related to behind the scenes algorithms (e.g. combating spam, ranking the front page, etc).

Could you please delete my account?

You just have to be around for some of them. Sometimes pg has done things to the UI of the site, then there is a large thread of community commentary, then it's kept, modified, or removed. If the feature shows up, and then goes away over the course of a day or two, you might miss that anything happened.

In the past pg has mentioned adding a feature to the running instance via a connected REPL, not the real source. If it proves its usefulness it goes in the source -- if not, the next restart removes it.

There are very many add ons and extensions and things available for HN.

There's bound to be a thread filtering add on for whatever browser you're using.
