Having someone do something other than squee is what takes it from fun to educational (while keeping the fun).
Very true. FF.net is not like the L&C community here. It would be wonderful if kids could see the process of writing that adults engage in - the use of beta readers, editors, reasoned debate. No one gets a story perfect on the first draft, and it takes an educated eye to effectively spot areas that can use improvement. Most kids I work with don't want to bother with revisions - it's almost as if "turned in" equals "good enough."
