Just Noticed a small change in Popdex: . I suppose in its aspiration to be different from Blogdex, it has changed the links format. Previously it showed the number of links that point to a particular story but now it has a PopScore, a pointing system out of 100 indicated by a la Google green bar. And instead of using Blogdex’s “track this site” words, it uses “Citations” to show the list of sites.
