I love blogs about learning. They provide quick snippets of information and fit nicely into a busy work day - just two or three minutes of reading allows me to keep learning and to stay on top of trends. Of course, ATD has a great selection of blogs you should check out!

• Check out one of the newest posts from Harvard Business Review on the topic  Proof that Positive Work Cultures are More Productive.
  
• The Rapid E-Learning Blog from Tom Kuhlmann presents great elearning resources as well as digital images and other visual offerings. It's helped increase my PowerPoint skillset tremendously! (You may have to sign up for a login, but it is free).
