The title is not very precise. I usually come up with the following situation.

I come up with a question after reading some materials and put it on MSE. Several days later, I get no answers and then I ask it on MO. But usually, I felt my question is rather elementary to those people on MO and receive not much help there. (Sometimes I felt embarrassed that I just deleted the "stupid" question.) 

Here are my **questions**:

 - How shall I improve my questions so that I might get help?
 - What do you usually do when questions posted on both sites get no answers?
