When I am viewing a question, the browser page title has the form:
Tag - Title
where "Title" is the question's title field, and "Tag", it seems, is the first tag (alphabetically) assigned to the question.
Why is this done? I don't see any value to it. Since there is no way to order tags manually (seem to be arrange alphabetically), the one tag chosen may not be significantly relevant to the question's essence. So why show one at all?
It makes it more difficult to locate a browser window or tab when some irrelevant word is dominating the tiny spaced allowed for a title...
