ClickZ has details on new services from PubSub.

PubSub is today expected to unleash a new site ranking tool, called LinkRanks, that measures the “strength, persistence, and vitality” of links pointing to and from a given Web site.

Additionally, PubSub has begun an effort to compile lists of influential Weblogs by category, which could be of use to media buyers and planners eager to buy advertising in blogs.
