Yammer / Twitter Use for Training?

Interesting blog article about using social media collaboration tools like Yammer or Twitter for training. If you have a group following a Course or Instructor, they can receive immediate notifications via the web, email, or even sms via their mobile phone. After putting your creative hat on it is not hard to see a savvy Trainer sending out reminders for upcoming classes, providing interesting links, inviting new hires to attend seminars, encouraging stimulating class discussions, and offering Yammer or Twitter as an online real-time help/support channel for students. Surely, this is informal learning at its very best? Happy yamming.
