heeeheee I found a logical bug in Wordpress. threaded comments are generated as nested lists; comments by postauthor get an extra class - which can be used for styling; now, when a comment is replied to by postauthor and that in turn by another user, that last comment *inherits* the 'bypostauthor' class - and styling gets a confused mess :D I can either write an override for the function that creates the classes and add a 'notpostauthor' class, or write much more specific (and complicated and fragile) CSS... # #
