Google Hangouts, Skype
Don’t always work perfectly, but when they work, they work great!
Google Hangouts: 1) regular video hangout (what was used in this session); need a google account of some kind, initiate hangout in the moment. Downside is technical issues. 2) Hangout “on air”. Scheduled in advance, system generates invite, recorded, and auto-archived, and generated on YouTube channel.
