I noticed earlier today that yahoo is using the nofollow tag in search results on it's version of site links. The "mini site links" that appear on a single line underneath the top site in some search results all have nofollow applied and it makes me wonder just how important nofollow is becoming in every day website internal link structures.
If this has been discussed before I apologize, a search returned nothing about nofollow in Yahoo's regular serps. Your thoughts?
