I try to answer this based on my experience, but I don't have any other source.

1. Favorite tags

• Don't aggregate more question of that type
• Change only the background of questions with that tag (if you did not search for them).

2. Ignored tags

• Are removed client-side (with JS)
• Just don't display.

I have a set of low-volume tags as favorites, so I only see a single question with a sqlite on stackoverflow.com.

Questions that have both ignored and favorited tags are ignored (I once ignored ns2 because it appears mostly with my favorite tag tcl, but I don't have the nessecary domain knowledge to answer most of them.)
