It can be difficult to write in a foreign language and I suspect that English might not be your first language. It will understandably take you a few minutes more than a native speaker to write an introduction, so the standard might be a bit lower -- but is that really you making an effort? SUO requires a minimum of effort on your part to give you the opportunity to take advantage of many hours of effort by the people who wrote the scripts available for free on this website.
