Three no-no's that will pull a reader out of a story.

When it comes to writing, there are a lot of rules. Otherwise, would we spend so much time in school studying languages?  Not all of the rules are written though. When writing fiction, here are three basic rules not to break.
1) Don't be cliche, nothing will hang the reader up faster than a tired cliche. The problem with cliches is they are so overused, they loose their meaning. Worse case scenario, said cliche reminds readers of other works they are used in. This can give an unintended message. I read a book which used a cliche that screamed Spider-Man. The book was a YA fantasy, not a comic book. To be honest, leaving cliches in your writing can make the work clunky and sloppy.
2) Using a specific branded item in your story without giving it a physical description. This is in part realizing who your audience is. You probably don't have to describe an iPod touch, but if you said, "Sally drove her Saturn SL1," most people would have no clue what to imagine. One quick fix is to keep the object generic, you can still give it a description, but now you are allowing the reader to make their own decision about what the item looks like.
3) The ever obvious spelling and grammatical errors. I don't think I have to explain this one.
