As reflected by Can we please have a ruling about Emacs questions on Stack Overflow? and Emacs questions: Super User or Stack Overflow? Emacs questions are scattered over the Stack Exchange network. Even if some Emacs questions do no really belong on Stack Overflow it might be better to ask there since the chance of getting an answer is greater there because more Emacs gurus seems to hang out there. But this is wrong in trying to keep questions on topic. The problem is if you ask an Emacs question on another Stack Exchange site you run a greater risk of getting no answer. One way of trying to fix this problems is to promote Emacs related tags on other Stack Exchange sites to Emacs gurus. How can this be done?
Can following Emacs related tags on other sites be promoted to Emacs gurus? Can Emacs filters, such as http://stackexchange.com/filters/281 but including more relevant sites, be promoted to Emacs gurus? How and where is it appropriate to make such promotion? On metas, in chat, externally? In short, what would be an appropriate way to highlight to the experts that there are Emacs questions on other sites?
My own experience with this problem comes from asking Emacs questions on TeX.sx. Often there is not enough competence to handle the Emacs aspect of such questions. Asking Emacs questions on Super User I have experienced that they seems to get less attention than if they were to be asked on Stack Overflow.
