  Thanks for providing the examples Seth. My previous comment was flagged as spam! Ahhhh!

We actually just created an infographic to showcase the incredible growth of Cloud Computing. As someone who write about Cloud Computing quite a bit I thought you may get a kick out of it :D Let me know if you'd like to check it out. Sam
