Ben has noticed that Technorati have started giving blogs an ‘Authority Rank’. The Top 100 list used to be base upon incoming links but now is based upon ‘authority’ (although I don’t see much has changed in that list so far).
There’s nothing about how they’re coming up with authority rankings yet on their blog – it’ll be interesting to see if this is just a new new name for the old ‘incoming links’ description or if they’re making bigger changes.
PS: It also looks like they’ve changed the way that blog’s profile pages are displayed. I don’t remember how the old ones displayed but here’s ProBlogger’s page. Now with screen shot of the blog, ‘blog reactions’ (what others are saying about the blog) etc.
I also note that they’ve started calling those favoriting a blog ‘fans’ which could indicate some more changes in the favoriting system are under way.
update: More on these changes are now on the Technorati blog
