I have been enjoying the various Google+ Hangouts and Hangouts On Air that are available in several Google+ communities.
The video below, from DearMyrtle, gives an overview of the differences between Hangouts and Hangouts On Air (HOA). Either format you attend, you will enjoy but I encourage you to try both. Hangouts and HOAs are similar to a webinar and are informative, educational and full of collaboration. Don't worry though, you can join without a webcam and still participate in the conversation.
I encourage you to visit GeneaWebinars to see a full list of the scheduled hangouts. Keep in mind though, a hangout can happen on the fly or with just a few hours notice. That is what is so great about hangouts, you can get into a discussion and hangout breaks out! The benefit being the screen sharing capabilities to help explain or clear up the topic under discussion. HOAs have the added benefit of being recorded and posted on YouTube. If you can't make the "live" HOA, no worries just catch it on YouTube when you can.
The possibilities for Google+ Hangouts and HOAs are endless. Be sure to give them a try. Once you become familiar with the format and the joining process I think you will be glad you did.
