I do not feel your current standards for questions are ok. I feel they require too high a level of prior knowledge and education. Far too often (in my opinion) people come here and ask a question only to be shut down for 2 avoidable reasons: 1) Too broad 2) Unclear
A person with a lack of knowledge that the Mod's have will frequently ask a question which is "too broad" simply because the poster doesn't know all the details involved in their question or all the thought and writings that have already exist.
I don't believe this instance requires the closing of a question, but rather the answering it to the level it is asked - and avoiding the nitty gritty details that the question is not actually asking about or aware of.
On the second point some people are not good at algebra, and other are not as good as writing or the English language (this is the web). If a question isn't as clear as we'd like that shouldn't mean that it is automatically closed, but I suggest rather we try to understand and answer to the best of our ability. Many times we can provide value this way that is lost when a question is closed.
While clearly stated and well researched questions provide the best opportunity for this site, I feel they should not be absolutely required. Too many people are left behind and great opportunities are lost to bridge the gap to those who are coming from a "blank slate" on their current knowledge of Christianity.
This site isn't a closed group of doctorate level members, but rather a world wide open forum for the discussion of Christianity which should encourage and respond to any question to the level the question is asked. Closing questions turns people of off Christianity and this site. Responding in the best way possible is a better approach in my opinion.
EDIT This question is poorly written, but can't it be answered? Surly there either is scripture that can be used to reference prayer at meals or there is nothing to support the topic or even a disagreement on it.
This is the only recently closed question I would put into the category I'm trying to define.
