Science fiction cliches to avoid

Via the always amazing SF Signal comes a link to 10 science fiction cliches to avoid. The only problem with the list is that it mainly focuses on science fiction cliches from TV and film. For a specific list of literary SF cliches to avoid, check out John VanSickle's amazing compendium. I love how he breaks the cliches down by a large number of categories, such as "items which flatly contradict the known laws of nature" and "items which were mildly interesting the first time around, but simply provoke a response along the lines of been there, done that on the re-runs."
