I'm really excited about Hangouts "On Air". I think there are a bunch of things I would change if I could. For example, I think the stream to YouTube itself should only show the focuses stream and not all of the multi-channels. I would also like to see the max number of connections in the hangout increased. An API would be awesome so I can generate Hangouts from a script.

After some more experience with running BostonRB's meeting over hangouts I'll follow up with a blog post on what we have liked and what pain points we've had.
