As I observed LaTeX has a separate site within stack exchange and a busy one at that. I was looking for similar information for DocBook and I did not find. DocBook questions are spread across multiple sites like unix and xml. It occurred to me that docbook probably needs a separate site. Although I am not an expert in the area, I am an information seeker on the subject and returned without answers.
So, why don't we have a seperate docbook site?
