I see. Now that you’ve mentioned that changed behavior in WP 3.0, does it mean that the hacks you’ve shown in this post are no longer necessary because they’re ‘built into’ WP 3.0?
This is puzzling because if it were so, how come most WordPress sites don’t display the “in reply to” info in the threaded comments. This is why I searched for code that does that and I landed here in your blog. :D
