Insofar as there is good news here, it’s that I’ve set the nesting to a max level of 4. So we should not break the time-space continuum here. But yes, the contrast in that reply link must be dealt with.

Oh yeah, that link text color vs. background color totally fails usability let alone accessibility.

On the plus side, nested comments are working. Something to potentially watch out for will be too many nested comments in 1 thread. In a WP blog that I’m an active participant in, we broke the blog once by too many comments/too deep of nesting.

Even if you do see the reply link, it takes a reply-to-a-reply to actually nest.
