Ask HN: What are Your Thoughts on Live Online Group Classes?

I've been kicking around this idea for a live online group class website. I'd love to tell HN about it and rip me apart.

The website would be a marketplace of live online classes for creative millennials and young adults. You would use group video chat to connect students and teachers from around the world.

A big problem with learning online is that the experience is lonely, boring and frustrating since you're learning alone without an instructor and classmates. The best way to learn is with others. Social experiences enhance learning and nothing can replace a great teacher or exploring ideas with fellow peers!

Here's how the site would work:

1) Browse for a live group class based on needs, schedule and interests. 2) Enroll and pay one-time fee for class. 3) Attend the class and learn via a live video group chat.

Here's a prototype to convey the idea: https://invis.io/ENDE1LGXT
