Since I'm going to check out of HN at the end of this YC cycle, this was my last chance to get this done. I didn't want the people who are going to inherit HN from me to have to build it as their first project, because it interacts with so many different bits of the code in such subtle ways.
So I found time to implement pending comments this past week, and with any luck it will launch tonight. Since it's a big change, I wanted to warn HN users in advance.
Here's how it currently works. From now on, when you post a comment, it won't initially be live. It will be in a new state called pending. Comments get from pending to live by being endorsed by multiple HN users with over 1000 karma. Those users will see pending comments, and will be able to endorse them by clicking on an "endorse" link next to the "flag" link.
Someone who has a pending comment will have to wait till it goes live to post another. We're hoping that good comments will get endorsed so quickly that there won't be a noticeable delay.
You can currently beat the system by posting an innocuous comment, waiting for it to be endorsed, and then after it's live, changing it to say something worse. We explicitly ask people not to do this. While we have no software for catching it, humans will notice, and we'll ban you.
Along with the change in software will come a change in policy. We're going to ask users with the ability to endorse comments only to endorse those that:
1. Say something substantial. E.g. not just a throwaway remark, or the kind of "Yes you did, No I didn't" bickering that races toward the right side of the page and no one cares about except the participants.
2. Say it without gratuitous nastiness. In particular, a comment in reply to another comment should be written in the spirit of colleagues cooperating in good faith to figure out the truth about something, not politicians trying to ridicule and misrepresent the other side.
People who regularly endorse comments that fail one or both of these tests will lose the ability to endorse comments. So if you're not sure whether you should endorse a comment, don't. There are a lot of people on HN. If a point is important, someone else will probably come along and make it without gratuitous nastiness.
I hope this will improve the quality of HN comments significantly, but we'll need your help to make it work, and your forbearance if, as usually happens, some things go wrong initially.
Is there some timeout? If not, commenting on a several-day-old thread will guarantee that you can never post another comment, since once threads drop off the front page it's not likely that many 1000+ karma users will even see those comments, never mind endorse them.
I'll add a pending page that collects pending comments. Maybe that will solve the problem.
If you really want to make sure that every post gets voted on you may need to do something like that to incentivize endorsements.
That's cool because I can imagine for a picture site you want all pictures to gravitate around the consensus, a strong self-selecting group-think can be very desirable.
But for HN ... well at least the people who end up sticking around will surely love it ...
There were a handful of people who had multiple points per vote who could swing it drastically away from the 'consensus' if it was wrong, and doing so also penalized the people who voted for it.
