This is interesting. Instead of competing with the myriad live-streaming vendors in the world, VideoLobby.com builds on top of them, allowing a publisher to use live video powered by Justin.tv, Ustream, Qik, and Stickam's Stream API.

The service integrates Twitter and Facebook chatter, as well as a form to ask questions of a host that's powered by a backend comment moderation system.

Some analysts say that VideoLobby.com seems somewhat superfluous, given those companies already integrate comments and social media themselves.
