Like Reddit comments with a thousand edits after they become popular.

Vimeo does have such a feature. The ability to do such could be based on karma on YouTube.

You're just farming more downvotes by clearly being affected by them and then complaining about them.

If this is how you respond to pointless vote counts, I would avoid revisiting comments after you leave them for the sake of your mental health.

> Please don't comment about the voting on comments. It never does any good, and it makes boring reading.

> Please don't submit comments saying that HN is turning into Reddit. It's a semi-noob illusion, as old as the hills.

I didn't leave a downvote, but that sounds like a horrible policy. You'd get a ton of short comments on the least-valuable (as judged by voters) comments, bloating the comment tree and making it way less readable.

It is fortunate, not unfortunate, that YouTube prevents editing of the video itself after a video has been uploaded, viewed, interacted with, shared, commented on, and started to accumulate karma of various sorts.
