When I am visiting the Ruby on Rails tag on Stack Overflow, I see only some questions as highlighted. Why so?

"Ruby on rails" is added in my favorite tag list. So it should highlight all the questions..

A preview (see full image here):

  • Are you sure you have ruby-on-rails selected and not just ruby-on-rails-3 and ruby?

  • Better, but more cropping would be welcome. Four lines should be enough to illustrate the point.

    @Suma I cannot cut the upper part because it shows what the fave tag is; this is the least! :)

When you're viewing the questions page under a favourite tag (as you are here), only questions that have another of your favourite tags as well are highlighted.

This holds even if you are viewing the questions under a combination of tags - there must be a further favourite tag for the question to be highlighted. So for me, when I view questions and then click over on the 'Related Tags' on the right, I get this list, and only questions with another of my favourite tags (above and beyond and ) are highlighted.

I only know this because I worked it out myself. I've gone looking for a reference for this, but the -tagged post about highlighting didn't mention this particular facet, so I've added it there.


The site does not highlight questions in a tag search unless they have another tag that you have also favorited. If it did highlight all of the questions tagged in your case, all of the questions would be highlighted. This would not emphasize any of the questions over any others, so the highlighting would be useless.
