In his recent post Roll with the Changes on PSMJ Resources Ed Hannan addresses the ever changing face of marketing. I especially like his thoughts on LinkedIn in the last four paragraphs. Namely, he and I agree that LinkedIn has become the business networking site of choice in the United States today. If you haven’t visited the PSMJ Resources blog recently it is well worth taking the time to explore. Also, Bruce posted a great blog today on the same site that will help you determine if you are a seagull manager. Thanks Ed and Bruce!
