I've noticed something odd when I change things in the admin area. If I go to the site to check it will have updated some of the pages with information added in a sitebar, but not yet on the homepage. It also seems that firefox is slower in refreshing than safari, but I am not sure why this is happening. New posts are immediately shown. I am using atahualpa theme, maybe there is something I should change to have the home page refresh faster? I am using wp-super cache (on half) but the issue occured already before I installed super cache..
