Ask HN: Is HN implementing a new comment ranking system?

was top rank for a while and then suddenly bottom ranked, even though more plus votes had been added. I am not for a moment complaining as I believe that some sort of system that removes top rank comments from remaining top ranked is desirable in many circumstances.
In some threads top comments tend to remain top because people read and rate them first, even though they may be far from the most "valuable" comment. They tend to stay top ranked because of inertia.
I am surprised that my comment was considered "worthless" but I don't care, just curious to find out if some tweaking is going on with the comment ranking - a good thing in my opinion.
