Introduction: I was looking at few SE sites and comparing 'How to Ask' instructions in the right sidebar that appear when you click 'Ask Question'.
What I found is:
- Stack Overflow: Is your question about programming?
- Serverfault: Is your question about servers, networking, or desktop infrastructure?
Both of these have a relation between the name of the site and the main filtering question.
What happened for me is that a pair (Stack Overflow, Programming) caused me to ask: Is it really only about stack-overflows? Checking the sample questions made me realize it is not, and that (among other things) lead me to read the FAQ eventually. I consider this a good thing.
With Server Fault something else happened: I thought I didn't need to read the FAQ. Another interesting thing happened there, too: I really did not have to! The filtering question is almost a perfect digest of what is on topic and what is not, with only few minor details cleared up in the FAQ. I consider this a good thing, too.
On EL&U we have:
- English Language and Usage: Is your question about English language and usage?
In the context of a newcomer, which means that the FAQ has not been read and fully digested and that only a sample of questions have been seen, I am wondering if this sentence is implying that any question about the English language and usage can be asked.
