1) UFS (United Feature Syndicate) apperantly complained about the cartoon RSS feeds; so the daily dilbert feed (formerly dilbert_feed) is gone and will probably stay gone.
This would really annoy people like katiebelle04 who select different userpics when posting. I'm annoyed because I don't like any page I'm viewing to change for any reason while I'm viewing it. (Mouseover menus are somewhat acceptable as they don't actually change the screen location of any content; but any page should be viewable in lynx (the non-frame one) just as well as in any graphical browser)
learn_support has some info on the subject, including linking to someone (killhamster) who has already expressed their dislike of the new comment reply system.
