Today's Tribune compiles a list of the "50 Best Web Sites"; Trib internet blogger Steve Johnson has put it online. I doubt more than, say, five of these will be new to our readers (sample inclusions: Defamer, Metacritic, The Onion), but your grandparents may find it a good place to get started on "that internet thing." That said, the paper is taking reader suggestions, so if you've got a favorite, plug it.
