Forums rarely get things right -- that had been solved by Usenet.

Proper threading.

Read/Unread tracking.

Keyboard UI. (And the mouse UI tends to be bad as well.)

Responsiveness. (Especially: page loads which are not instantaneous.)

Killfiles.

They generally have mediocre search functions unless they are entirely visible to Google.

These are off the top of my head.

Does usenet have points? That's what I find missing in most forums, except Reddit and HN, where best comments flow towards the top, instead of being present arbitrarily deep in the timeline.

Sorry, no native point system. You can bolt on something NoCeM-like, server or newsreader based, and enjoy distributing article reputation right now. But it supplies only a show/no show signal out of the box. I think the cancelmoose would have preferred it to be somehow more nuanced and only live in newsreaders...

I actually prefer having the thread with the most recent post at the top (or bottom depending on how one sorts it) of the list. That, I find is helpful in terms of keep up to date with the most recent comments. The equivalent in HN would be that the next time you load HN's front page, this particular article would appear at the top of the list and this comment (along with other new comments) would be highlighted when you load the comments section.

Thunderbird does this by default. Reddit breaks threading when sorting by "new". On HN, you have to search the comments page "minutes ago" or "hours ago" to find new comments in an existing thread.
