Recently I've posted my first question on SU, which was closed for being offtopic.
Now, when I wrote the question, the entrybox warned me that the title might be offtopic, so I'm very aware of that. However, I assumed that whoever would encounter this question would rather not blindly close it, but instead read the question, and decide afterwards... Either this did not happen in this case, or my question is/was indeed offtopic.
When clicking the mp3-player tag, one will most likely notice that there are some similar questions, which did not get closed.
So my question is, When is a question on SuperUser ontopic, and when is it offtopic?
