This is one of those typical HN replies that adds absolutely nothing to the discussion.

Much like your own, and this one!

I wonder if this ritual of meta-self-policing serves some particular purpose or if it's just a case of the brain drawing comfort from going through a familiar ritual. "This comment adds nothing" is like the reverse amen in church of our days.

Another example of context collapse. Meta-meta commenting always adds something if only unironically.

The purpose was to discourage comments which added nothing I thought.

The GP comment adds social pressure so useless comments are less likely to be made.

It's a discussion, it's not a panel to further scientific inquiry. Sentiments and opinions also further a discussion.

It confirms for me that I too made the right choice and it reminds people that haven't made the jump yet that they have a choice in how their operating system treats them. I'd say it added a lot more than your comment.
