Should we stop adding the most popular tag to the HTML title on every SE site?
I do not think tags should be included in page titles. Currently, page titles are in the form tag - Question Title
. I think the tags should be omitted because it can make it difficult to tell which question is which if you have more than one question with the same tag open at once.
In this image, I have the Newest Questions page on the left, and four questions tagged c++ on the right. Can you tell which questions are open? I certainly can't; all I see is C++ and part of the first letter. This is even worse with long tags.
Tags are good for organizing questions, but they do not make good page titles.
