Proofread something once yourself and after that don't. Pass it along to any new set of eyes you can get and get a new perspective on it. Your eyes will fail you very quickly, so getting new people will make anything you write better by a large margin each time. Edit: Not a YC alum, but I thought I'd leave a note anyway.
