After a night cruising from MSM through blogs and some twittering, I cannot help but to reflect on changes in communications. Barack Obama has accepted the Democratic Party nomination in a reaching speech at Mile High Stadium in Denver on the 45th anniversary of Dr. Martin Luther King’s “I have a dream” address. Would you have thought we would see an African American nominated as president of the United States?  Even more remarkable, perhaps, is effectiveness of new media in energizing this campaign and a massive amount of funding from individuals.Going forward, we will see more - not fewer - changes in politics, business and society enabled by these technologies. There is so much written about these technologies. One of the best explanations of them appeared in a blog called hearitfrom.us  Not fancy. But clear.
