Paul Gillen, who has transformed himself from a journalist to a social media guru, has some advice for B2B companies in BtoBOnline magazine. His "Tap into social communities: 5 tips for marketers seeking to connect with prospective customers online" doesn't provide new ideas. But it does provide come interesting mini-case studies -- and that can be useful when talking with clients or others who might be reluctant to jump into social media.
Lead generation continues to be a big issue for many clients, and Gillin does provide a good case study of using social media to generate leads.
It's worth reading.
