It seems that wherever I look online looking for interesting conversations on business use of social media, I find Dennis Howlett, not just participating but as a top contributor. An accountant by discipline, he has emerged as one of the most knowledgeable and generous thinkers on the impact of social media on the Global Enterprise.
He has taken my SAP Global Survey questions and posted his answers on his AccMan blog. He also has an excellent recent post on FaceBook and the Enterprise as a guest editor over at ZDNet's Between the Lines news blog.
