B2B Tomorrow uses technology provided by SocialRank to monitor business-to-business web sites and find the most popular posts and the most popular B2B blogs overall. Top posts recently include Is You Tube Inappropriate for Business Video? from the Marcom Writer blog, The Hierarchy of Social Marketing from Duct Tape Marketing, and The real business model for Web 2.0: corporate clients from Forrester Research’s Groundswell blog. As you might expect — and as you can see from the list — most of the entries are from B2B marketing blogs. But as you can also see, there’s potentially useful information there for editors and publishers trying to reach an audience.
