I would like to chime in here and mention that the original poster of the question is irrelevant in any case.
Why would one want to know who asked the question -
- Will it make you look at the question differently?
- Will you misunderstand the question because you do not know exactly who asked it?
- Would knowing who asked the question affect your decision to answer it?
If the answer to any of those is yes then I'm afraid you are not looking at the content on Stack Overflow in the right way... Content on the site should stand on its own merit. The user who is attached to that post has nothing to do with the validity of the question*.
Content is content no matter what user submitted the post. Think about a situation where a user posts a terribly formatted and worded question... The community will jump on that post, make edits, retag, etc.. until the question is much much better and meets our high quality standards. Other than thinking up the question, the original poster had nothing to do with the final outcome of his post - tags were added, formatting was changed, etc...
I'd like to address one statement you made -
you want to give time to questions specific to your experience and asked by reputed person
A reputed person (I assume from the context) is a user with a relatively high reputation. Think about this - I have most of my rep from **book questions... but I have zero knowledge in C#. I'm able to ask an extremely complex **book FQL/Graph API question but I might ask a painfully simple C# question... A high rep user can still ask simple simple questions in a field that he is not experienced... So you see - the user doesn't really matter here - its the content of the question you need to look at...
So you see, the fact that you want to see who originally posted the question (before even looking at the question) is the wrong way to go about things... Judge questions by their content and not by the users...
* Unless of course the same user is re-posting questions.
