Google Hangouts is an exciting new platform to interact with people all over the world and in my personal opinion, it is much better than Skype. I recently took two webinars for students all over the country regarding the USMLE exams using this platform. The live feed and the recording were watched by a lot of students and http://www.internetmedicine.com even wrote a story about my webinars.
Dr. John Bennett, a retired doctor based out of Miami organizes these hangouts regularly on various topics. He has been encouraging doctors to use this platform and share their knowledge with students/ colleagues all across the globe.
