For me, this is a social networking platform, at least partly. If they never comment, of course I care. I like the votes, because it means (probably) they approve, but comments are the glue that hold connections together.

I'm retired. You're at the computer all day. We have the time to read and comment. Not everyone does. I try not to judge, but I do love comments.

I do notice when all the VP is delegated, but it doesn't bother me too much.
