Search Engine Optimization Eblog

This is just a new building block that lets software makers have better granularity--at a link level instead of a page level. And they can declare things about the authorship of a link that they couldn't before. Lots of people are using it to do smart things; for example, LiveJournal can recognize authenticated users and they won't get the nofollow tag. So it's not the case that every comment or trackback will be reduced in value. Last week, a software maker didn't have that ability, but now they do.

In other words, if you trust a user or like their comment, it won't be hard for them to get search juice from commenting on your posts. I believe that adding this flexibility for software makers will be a very helpful thing in the long term.
