As of today some questions show on the main page with a blue background. Why?

  • It's not questions I've viewed.
  • It's not questions I've responded to.
  • It's not questions where I commented on someone's answer.

So what is it?

  • Do you have any favorite tags selected? Jul 23, 2011 at 22:11
  • No. I just checked and I've nothing selected.

This is highlighting questions with tags that are in your favorite tags. If you haven't manually added any favorite tags, the system will detect when you have a certain level of activity in a tag and infer one for you. If you manually add a favorite tag, the system will not infer tags for you.

You can customize your favorite (and ignored tags) in your profile. You can also customize these settings in the right sidebar of the homepage and the /questions listing.

So, if you would prefer not to have any questions highlighted, you can simply add a nonsense "tag" to your favorites. Perhaps ? (:

  • @Rebecca Yes, thanks - I wasn't aware of this inferring functionality, either. (Of course, I had a few tags set as favorites, so I didn't notice.) Jul 23, 2011 at 23:37
  • @gef just to be clear, you do have to visit a lot of questions with a specific tag for it to become an inferred favorite tag. So it is not coincidental, for the record. :) Jul 24, 2011 at 9:35
  • @Jeff. No worries; makes sense.

  • @jeff How many is a lot? It hasn't inferred any tags for me, nor do I have any specified manually. Jul 27, 2011 at 9:19
