Twitter. It's everywhere. Newscasters mention it. Political analysts point to its influence. Marketers use it to get messages out. Journalists and bloggers use it for research. Regular folks use it to keep up with their friends, family, and co-workers. And, people of all types use it for entertainment, research, and education. But, Twitter is more than all of these things combined. It's a revolution in content publishing and its changing forever -- or at least for now -- how we communicate what's important to us to those who want to know.
