Techcrunch has this breaking news about a new application of Google Hangouts designed for showing and teaching things. Helpouts are like Hangouts, but designed for small businesses. Once they work out a way to collect money, the author thinks will be a boon for online tutors of all stripes. All those conversation lounges may just have more competition.
Not sure where they got the screenshots from, and the launch date has not been announced, but something to watch for.
