What if Khan Academy did livestream sessions?

That's definitely an interesting idea!

Unfortunately, I don't foresee something like this being implemented anytime soon though, mainly due to cost and performance reasons. For now the best way to ask questions is through the discussion threads beneath videos. There's a lot of users that look through those threads and help answer questions, so posting in the discussion threads should help get some of your questions answered!

Thanks for the feedback and suggestions!

Also, since this is a worldwide community, there would be issues with time zones.
