Starting around the same time comment scores were hidden, people have been voting less on comments, and it often seems like few people even read your comments in threads not on the front page. What this effectively means, especially in less active threads, is that I can only hold conversations with people if they have >1000 karma. Others will simply fade into the ether.
A slightly less bad approach would be if the popularity of the thread determines the threshold for posts needing endorsement. So as an example, non-front-page threads get posts from people with >50% endorsement rate and >20 endorsements immediately live, threads on the bottom half of the front page get posts from people with a >75% endorsement rate and >50 endorsements immediately live, and threads in the top half of the front page have everyone go through endorsement. Or maybe the number of posts already in the thread determines those thresholds. The issue with that is that in a thread with 200 comments, I'm never going to look at all of them, or even a quarter, so any that need endorsement will likely be missed.
Another possibly less bad approach would be to start posts at 0 points if the poster is under a relatively high karma threshold.
Also, after 24 hours, all "non-endorsed" posts should go live with an indicator, not disappear, so we can see if the system is even working as intended, and have one last chance of finding those hidden gems.
That said, you will be missed, Paul! I hope we'll still see you post from time to time.
