On the website, we have many brand names in form of the website's names, publishers, etc. exists; however, we have a more general tag each of them. For instance, we have elsevier with only 6 questions tagged or scopus while we have a publishers tag with 52 questions tagged. The same also situation exists for facebook, twitter, etc. with no more than 10 questions tagged; while we have a more general tag social-media.
My question is, what is the role of having such brand name tags on the website, while we have good general tags as well? And, what can we do to have more orginised tags when we can have a general tag and we already have brand or website names tags on Academia?
