I have a problem with the greyed out posts because they are difficult to read with my poor eyesight. I usually select them with the mouse so they are highlighted, which makes them easier to read.
I always assumed that's what you were supposed to do anyway. If it's just slightly downvoted it is still somewhat readable but after that it gets hard to read quick. I don't think this has much to do with eyesight, it's by design. I guess poor eyesight might make it hard to distinguish between normal and slightly downvoted comments, but that's not too important a distinction anyway.
Yup. This is my precise annoyance with the styling. I understand not everyone will bother to read greyed out comments because they trust the wisdom of the crowd here. I do not. As a result, reading the comments adds one extra step now just to interact and engage.
