Do you reply to all comments?

I am EXTREMELY fortunate that I have a lot of very lovely, engaged readers for my only fic.

In the beginning, I would respond to every comment that came in with at least something. But now that I get like 40-65 comments on each chapter, it’s kind of a lot.

I love the comments and each one gives me a little rush when I see them so I don’t want to discourage anyone from leaving them. I do still reply as much as I can (I occasionally miss whole chapters of comments, but I try to make up for in the next one).

I considered having some set replies to use for the more generic comments, but I don’t know if that’s better or worse than not replying at all?

Looking for insight from both readers and writers on preferred comment etiquette.
