The help center states that questions about "general knowledge (science, etc.) as it relates directly to Judaism" are acceptable.
My question is: how direct.
I am asking particularly about questions about activities based in Jewish observance, whose answers ultimately lie outside the realm of religion.
For example: "What is a good way to stay awake on Shavuot night" (I made this question up on the spot). The real question is how to stay awake. Staying awake might just happen to be useful to Jews practicing Judaism.
Related to different degrees are: Is there a way to minimize soreness or getting a lip blister from blowing the shofar? and How do I avoid thirst when fasting? and How can you quit a habit of visiting inappropriate websites? and many more.
The last one would not have been included in my listing had it been phrased: "what do Jewish sources say about...".
However, without such additions the questions are asking about blisters, fasting, and addiction respectively, rather than, for example Judaism's take on these.
