On JoeUser classic no one could even comment on a blog.  No matter how obnoxious my opinion was on some topic, no one could come on and say "Hey, you may not like your Mac but at least it's not constantly infected by worm viruses!" or something like that.  Now, on the new JoeUser.com, you can.  On anonymous comments I do have the right to delete them (so no more "Go back to Russia!" comments <g>) but you don't have to actually create an account now to drop in a post.
